Повний текст джерелаInfrared laser light radiation may be used to depolarize neurons and to stimulate neural activity. The underlying mechanism of such stimulation is believed to happen due to a photothermal interaction. The absorption of the infrared radiation by the targeted biological tissue inducing a local temperature increase which either directly influence membrane properties or act via temperature sensitive ion channels. Action potentials are typically measured electrically in neurons with microelectrodes, but they can also be observed using fluorescence microscopy techniques that use synthetic or genetically encoded calcium indicators. In this work, we studied the impact of infrared laser light on neuronal calcium signals to address the mechanism of these thermal effects. HT22 mouse hippocampal neurons and U87 human glioblastoma cells were used loaded with the fluorescent calcium dye Fluo-4 and with the temperature sensitive fluorophore Rhodamine B to measure calcium signals and temperature changes at the cellular level. Here we present our all-optical strategy for studying the influence of infrared laser light on neural activity, and the scientific approach leading to conclusion of the involvement of Phospholipase C activity during infrared neural stimulation. The ability of infrared exposure to trigger neural activity in mice brain in vivo is also investigated with the use of GCaMP6s transgenic mice

Infrared spectrum, especially mid-infrared range (2.512tm) covers the absorption peaks of many important chemicals including carbon monoxide, methane and water vapor. By analyzing the absorption spectrum of achemical, one can measure the concentration of the chemicals as well as distinguish the chemical species. The purpose of this work is to build a Si CMOS compatible integrated mid-infrared (MIR) platform for sensing. In this work, we evaluated the three major components (materials and devices) comprising an integrated mid-infrared (MIR) sensing platform: the light source, the waveguide sensor and the detector. To build an integrated MIR light source, we evaluated three approaches. 1) Germanium light source, which is the representative of the CMOS compatible semiconductor light source. By applying tensile strain as well as increasing doping and injection level, Ge is tuned to pseudo-direct or direct bandgap structure and the emission wavelength extends to MIR range. 2) Er-doped GaLaS (GLS) platform which is the representative of the rare earth doped material system. A new laser structure is designed for this system with a threshold power of 7.6 ptW and a slope efficiency of 10.26%. 3) Frequency comb generation which is a new area using nonlinearity to generate new frequencies. Thick Si3N4 material for comb structures are designed, fabricated and tested. In the waveguide sensor section, a waveguide structure based on chalcogenide glass (ChG) is built and tested. The sensing limit for methane reaches 2.5 vol. %. Besides, a ChG based small-footprint plasmonic optical switch is designed to work as an optical router for integrated spectrometer applications with a small (167 nm long) footprint. In the last part, a MIR PbTe based integrated detector has been successfully demonstrated for the first time. A further improvement in the material property and device structure yields a responsivity is about 1.4 A/W in the MIR regime.

Повний текст джерелаLa capacidad de manipular la frecuencia de la luz, a través de sintonizables fuentes de conversión de frecuencia paramétrica basadas en materiales no lineales del tipo ¿(2), ofrece un acceso eficaz a las regiones espectrales inaccesible por los láseres convencionales. Entre los dispositivos sintonizables más importantes, los osciladores ópticos paramétricos (OPOs) de onda continua (cw) en el infrarrojo (IR) con ancho de banda estrecho, son fuentes esenciales para muchas aplicaciones en espectroscopia molecular y metrología de precisión. Con el fin de explotar tales aplicaciones, es muy deseable el desarrollo de OPOs de cw mediante diferentes esquemas de sintonización de longitud de onda y nuevos materiales no lineales, como se presentan en esta tesis. Mostramos aquí un OPO de cw rápidamente sintonizable basado en un cristal periodically-poled KTiOPO4 con diseño de red fan-out a temperatura ambiente. Este enfoque permite una sintonización continua de la longitud de onda evitando el aumento de las fluctuaciones térmicas a temperaturas de funcionamiento más altas de los cristales. El OPO resonante con acoplador de salida bombeado a longitud de onda de 532 nm, proporciona radiación sintonizable en el infrarrojo cercano (near-IR) a través de 741-922 nm y 1258-1884nm, con una potencia de salida máxima de 1.65 W. El uso del acoplador de salida para la onda resonante reduce la carga térmica y permite una mejora del 30% en la eficiencia de extracción del OPO sobre la configuración SRO pura. Con el objetivo de desarrollar la nueva generación de fuentes de onda continua con longitud de onda >4 µm utilizando la técnica de quasi-phase-matching con materiales semiconductores, presentamos la primera demostración de una fuente de onda continua sintonizable en el infrarrojo medio (mid-IR) utilizando el patrón de orientación de fosfuro de galio (OP-GaP) y generación de frecuencia diferencia (DFG) entre láser de fibra Tm a longitud de onda de 2010 nm y otro OPO hecho en el laboratorio basado en un cristal MgO-doped periodically-poled LiNbO3 (MgO:PPLN). La fuente DFG genera hasta 43 mW de potencia de salida, con >30 mW a través de un 96% del rango de sintonización 4608-4694 nm, con una alta calidad de haz. A medida que las fuentes de emisión en el mid-IR sintonizables mejoren sus prestaciones, la disponibilidad de detectores de mid-IR rápidos y sensibles se vuelve igualmente importante. Sin embargo, los detectores de mid-IR convencionales requieren sistemas criogénicos para operar con poco ruido, lo que presenta un gran inconveniente ya que estos dispositivos suelen ser voluminosos y caros. En este contexto, la técnica no lineal de conversión ascendente de frecuencia ha surgido como una alternativa prometedora a la detección directa de la radiación de mid-IR a temperatura ambiente. Un detector de conversión ascendente (UCD) se puede optimizar aún más dentificando y suprimiendo sus fuentes de ruido. Para hacerlo, investigamos teórica y experimentalmente las propiedades de ruido de un UCD de un solo paso bombeado a 1064 nm diseñado para la detección de señales en telecomunicaciones y rango mid-IR, utilizando cristales MgO:PPLN. Descubrimos una nueva fuente de ruido llamada ruido espontáneo paramétrico de conversión descendente inducido por generación de segundo harmónico SHG (SHG-SPDC). Estudiamos, también, la dependencia de la intensidad de este ruido (SHG-SPDC) con la potencia de bombeo y la temperatura del cristal. Finalmente, también comparamos su intensidad con el conocido ruido generado por el detector UCD, llamado ruido de conversión ascendente por conversión paramétrica descendente espontánea (USPDC). Los resultados obtenidos nos dicen que se debe considerar cuidadosamente el SHG-SPDC, ya que puede actuar como una fuente de ruido dominante en ciertas condiciones de operación. Sin embargo, el SHG-SPDC se puede evitar al elegir una combinación adecuada de MgO:PPLN, el período de red la temperatura de operación y el filtro de tipo pasa banda.

Повний текст джерелаThe increased usage of infrared sensors by pilots has created a growing demand for simulated environments based on infrared radiation. This has led to an increased need for Saab to refine their existing model for simulating real-time infrared imagery, resulting in the carrying through of this thesis. Saab develops the Gripen aircraft, and they provide training simulators where pilots can train in a realistic environment. The new model is required to be based on the real-world behavior of infrared radiation, and furthermore, unlike Saab's existing model, have dynamically changeable attributes.
This thesis seeks to develop a simulation model compliant with the requirements presented by Saab, and to develop the implementation of a test environment demonstrating the features and capabilities of the proposed model. All through the development of the model, the pilot training value has been kept in mind.
The first part of the thesis consists of a literature study to build a theoretical base for the rest of the work. This is followed by the development of the simulation model itself and a subsequent implementation thereof. The simulation model and the test implementation are evaluated as the final step conducted within the framework of this thesis.
The main conclusions of this thesis first of all includes that the proposed simulation model does in fact have its foundation in physics. It is further concluded that certain attributes of the model, such as time of day, are dynamically changeable as requested. Furthermore, the test implementation is considered to have been feasibly integrated with the current simulation environment.
A plan concluding how to proceed has also been developed. The plan suggests future work with the proposed simulation model, since the evaluation shows that it performs well in comparison to the existing model as well as other products on the market.
