Résumé :
Cavity ring-down spectroscopy is a spectroscopic method that uses a high quality optical cavity to amplify the optical loss due to the light absorption by a sample. In this presentation we highlight two applications of phase-shift cavity ring-down spectroscopy that are suited for absorption measurements in the condensed phase and make use of waveguide cavities. In the first application, a fiber loop is used as an optical cavity and the sample is introduced in a gap in the loop to allow absorption measurements of nanoliters of solution at the micromolar level. A second application involves silica microspheres as high finesse cavities. Information on the refractive index and absorption of a thin film of ethylene diamine on the surface of the microresonator is obtained simultaneously by the measurements of the wavelength shift of the cavity mode spectrum and the change in optical decay time, respectively.

Résumé :
Abstract Terahertz parametric oscillator (TPO) with a rhombic ring-cavity is demonstrated. The oscillating cavity is composed of three mirrors and the terahertz emitting-surface. Terahertz frequency can be tuned from 0.9 THz to 2.9 THz just by shifting the position of a cavity mirror. Under a certain round-trip optical length of the Stokes beam, the pump beam size can be larger in the rhombic ring-cavity TPO than that in the conventional resonant-cavity TPO. The maximum terahertz pulse energy in the rhombic ring-cavity TPO is 3.21 μJ, which is about 3 times higher than that in the conventional resonant-cavity TPO.

Résumé :
The effect of semiconductor saturable absorber mirror (SESAM) on continuous-wave multi-wavelength fiber ring-cavity laser with semiconductor optical amplifier (SOA) is experimentally demonstrated. The evolutionary process of multi-wavelength oscillation and the decrease of oscillating mode number caused by an SESAM are discussed. It’s found that the free oscillating mode number of the multi-wavelength fiber ring-cavity laser with SOA can be upto three, and the lasing wavelengths are 1573.8 nm, 1578.09 nm and 1582.37 nm, respectively. When a SESAM is inserted in the fiber ring-cavity, it narrows the amplified spontaneous emission (ASE) spectrum of the SOA, and the oscillating mode number of the multi-wavelength fiber ring-cavity lasers with SOA decreases to two, a stable dual-wavelength lasing at 1560.91 nm and 1564.12 nm is obtained.

Résumé :
A developed spectrometer based on optical-feedback cavity ring-down spectroscopy (OF-CRDS) has been demonstrated with a distributed feedback laser diode and a V-shaped glass ceramic cavity. The laser is coupled to the V-shaped cavity, which creates an absorption path length greater than 2.8 km, and resonance between the laser frequency and the cavity modes is realized by modulating the cavity length instead of tuning the laser wavelength to obtain a higher resolution. A noise-equivalent absorption coefficient of ∼2.6 × 10−8 cm−1Hz−1/2 (1σ) is determined with spectral resolution of ∼0.003 cm−1 and spectral range of 1.2 cm−1. As an application example, the absorption spectrum measurement of water vapor in the spectral range of 6590.3∼6591.5 cm−1 is demonstrated with this spectrometer.

Résumé :
A fiber ring-cavity laser based on InP/InGaAsP multi-quantum wells semiconductor optical amplifier is proposed and experimentally demonstrated. The laser uses InP/InGaAsP multi-quantum as well as the gain medium and fiber Bragg grating as the wavelength selector. It’s demonstrated that the center wavelength of the output amplified spontaneous emission spectrum for the InP/InGaAsP multiple-quantum wells appears blue shift when its injection current increases. A lasing at central wavelength of 1549.66 nm with the maximum output power of 1.524 mW is obtained with electro-optical efficiency of 1.1% at injection current of 220 mA and the fiber Bragg grating operating temperature of 23[Formula: see text]C. The threshold injection current of the laser is 78 mA. When the operating temperature of fiber Bragg grating increases from 8[Formula: see text]C to 28[Formula: see text]C, the center wavelength of output laser increases from 1549.27 to 1549.59 nm. It shows that the laser has good temperature stability.

Résumé :
A continue-wave cavity ring down experimental system is established surrounding the micro-sphere cavity. In the experiments of measuring micro-spheres cavity quality factor (Q) upon the system, it is found that photoelectric detectors with different response characteristic have different response to the optical signal which is shut off rapidly. The vibration noise caused by changes of external environment, meanwhile, can be transformed following the change of photoelectric detector properties. With the build of photoelectric detector response model, the mean-square deviation of repeated experiments under the same conditions is used for charactering level of the error caused by vibration noise. The influence of vibration noise to photoelectric detector is discussed in detail, and further analyzes the effect for the cavity ring down time extraction. Then the optimal photoelectric detector (Newfocus1434, 15V/W) is selected to optimize the experimental system. The level of error caused by vibration noise has been decreased from 0.191ns to 1.562ps. Finally, the Q value of micro-sphere cavity is calculated according to fitted value of cavity ring down time, and the experimental correctness is verified by the line-width law.

Résumé :
Cavity ring-down spectroscopy (CRDS) is a highly sensitive molecular absorption spectroscopic technology, which has been widely used in mirror reflectance measurement, atmospheric trace gas detection, molecular precision spectroscopy and other fields. It deduces the intracavity absorption by measuring the rapid variation of the ringdown signal. As a result, detector with high linearity, broad bandwidth and low electrical noise is indispensable. Additionally, owing to the large noise in laser frequency, low laser-to-cavity coupling efficiency is obtained. Consequently, the cavity transmission is faint, which deteriorates the detection sensitivity. Optical feedback can address this problem by locking the laser to the cavity longitudinal mode. Then, the laser frequency noise is suppressed and hence better detection sensitivity is expected. Optical feedback CRDS with V-shape cavity has been widely studied. Compared with Fabry-Perot cavity, this cavity geometry is very sensitive to mechanical vibration and possesses low degree of fineness due to an additional mirror. In this paper, optical feedback linear cavity ring-down spectroscopy based on a Fabry-Perot cavity with a degree of fineness of 7800 is presented. The principle of the combination of optical feedback and linear cavity is explained from the perspective of the light phase, which shows that the reflection will not generate efficient optical feedback if the feedback phase is appropriately controlled and laser to cavity locking can be therefore realized. And then, the factors influencing the stability of ring-down signal are analyzed, including the feedback ratio, the trigger voltage for the ringdown event, and the distance between the light spot and the detector center. The experimental results show that a superior fractional uncertainty of the empty ringdown time of 0.026% can be obtained with a low feedback rate (3% FSR), a high ringdown signal trigger threshold (90% cavity mode amplitude) and superposition of the light spot with the detector center. With Allan variance analysis, the white noise response of 1.56 × 10<sup>–9</sup> cm<sup>–1</sup>/ Hz<sup>–1/2</sup> and the detection sensitivity of 1.29 × 10<sup>–10</sup> cm<sup>–1</sup> for trace gas detection can be achieved in an integration time of 180 s, corresponding to the lowest CH<sub>4</sub> concentration detection of 0.35 ppb at 6046.9 cm<sup>–1</sup>. This robust spectroscopic technique paves the way for constructing high-sensitive and stable-cavity based instrument for trace gas detection.

Résumé :
To meet a high-precision accelerometer resistance of temperature, humidity and other external noise, a new multi-ring cascade optical accelerometer structure is designed. The micro-ring resonator on the cantilever beam based on the photo-elastic effect and the contrast are fabricated with the same manufacturing process and size, which can effectively meet the consistency of the contrast and test micro-ring resonator on the cantilever. The one resonance point curve will split into two under the acceleration, thus the acceleration value can be obtained by detecting the wavelength of the two resonant points. By testing the cascade race-track shaped micro-ring resonator at different temperatures, the Q=104, the test requirement of cascade race-track shaped micro-ring accelerometer in different environments is greatly met. The design can be widely applied to the occasions of penetration system with high impact, strong vibration and so on. And the anti-noise and anti-jamming features of the integrated miniaturized high-sensitivity MOEMS sensors are realized.

Résumé :
Resonance properties of the all-fiber ring cavity filled with nonlinear material - saturable rare-earth-doped fiber are analyzed and experimentally investigated. Unlike the earlier investigated erbium-doped fiber at 1550nm where the optical absorption photo-induced change (saturation) is observed only, the ytterbium-doped fiber at 1064nm demonstrates the saturation of the refractive index mainly. For this configuration we report experimental observation of the optical bistability and hysteresis in the transmitted output light at the 10mW-scale incident light power. The experimental results are in qualitative agreement with the theoretical analysis that takes into account the saturation of both parameters: the optical absorption and the refractive index of the doped fiber. The reported results seem promising for applications in high-sensitivity interferometric configurations at 1064nm operation wavelength.

Résumé :
MEMS accelerometers utilizing electrostatic, piezoelectric, and magnetic proof mass displacement readout approaches have achieved success in both commercial- and defense-related applications. However, there is a desire for improved acceleration resolution suitable for navigation-grade applications. Optical readout of mechanical displacements has demonstrated high levels of resolution in macro-scale applications including precision movement and placement systems. In addition, optical techniques are common in high performance inertial sensors such as fiber optic gyros and ring laser gyros. Incorporating optical readout approaches into MEMS acceleration devices may yield sufficient resolution to achieve navigation-grade performance. Therefore, the U.S. Army AMRDEC is developing MEMS accelerometers based on optical cavity resonance readout. In the device, an optical cavity is formed between a MEMS proof mass and a reference reflector. A tunable laser excites the cavity on the edge of its resonance peak. Small displacements of the cavity from its rest position are detected by frequency shifts of the resonance, leading to high-resolution proof mass displacement detection and therefore high acceleration resolutions. This paper will present modeling associated with the design concept, as well predictions of device geometries and performance with the goal of achieving less than 1 micro-g bias instability and a velocity random walk of better than 0.2 micro-g/rt.Hz.

Résumé :
Abstract We propose a method for thermal expansion compensation of reference monolithic optical cavities for laser frequency stabilization. Two schemes of optical cavities are considered: a Fabry–Perot interferometer with a crimp ring and a whispering-gallery-mode cavity with a clamp. In each scheme, thermal expansion compensation is achieved due to the strained connection of the cavity with an element made of a material with a high coefficient of thermal expansion. The temperature range of the cavities’ optical length stabilization is estimated.

Résumé :
We theoretically investigate a 25 GHz multichannel filter based on ring cavity birefringent optical interleaver for dense wavelength division multiplexing (DWDM) transmission systems. The simulation tool used in this work is the Advanced System Analysis Program (ASAP) optical modeling software. We improve the dispersion performance by employingλ/6 andλ/4 wave plates as birefringent compensators for interleavers. The new structure exhibits a high performance with nearly zero ripple, a channel isolation greater than 102 dB, and a passband utilization of 86% within the C-band. The research results illustrate that our modified scheme can improve the dispersion of more than 76.6% in comparison with the previous studies of optical interleaver with birefringent crystal and ring cavity structures.

Résumé :
Abstract The linear absorption in erbium-doped fiber (EDF) contributes to its excellent role in EDF amplifiers and lasers. A nonlinear optical contribution in the absorption of EDF is responsible for optical bistable action when it is present in a laser cavity. To quantify this effect, the variation of absorption coefficient is measured at different signal powers at multiple wavelengths in the C-band for different EDF lengths, and saturable absorption parameters such as the saturation power are extracted. Then the modification in the output characteristics of EDF ring laser with change in fiber length and in the presence of self-induced saturable absorption effect within the gain medium, which leads to optical bistability, is measured. By comparing the measured parameters obtained from saturable absorption in EDF and optical bistability in EDF ring laser, we estimated the length of the gain medium which acts as the saturable absorber inside the cavity of the laser. This is useful in constructing bistable lasers with optimized conditions. The temporal evolution of cavity loss and gain with the intra-cavity power and up- and down-thresholds helps in understanding why the down-threshold will be lesser than the up-threshold in bistable laser systems.
