Nguyen, Duy Duc. "Modeling a micro-mirror array and contribution to the development of a simulator of micro-system arrays." Thesis, Bourgogne Franche-Comté, 2017. http://www.theses.fr/2017UBFCD087.
Повний текст джерелаIn this thesis, we contribute to the modeling, simulation and optimization of a new generation of micro mirror arrays designed by the Astrophysics Laboratory of Marseille (LAM). A contribution is also made to the development of MEMSALab a symbolic computation software package designed to asist multiscale model derivation for microsystem arrays. The coupling between the quasi-static nonlinear behavior of a cell of the micro-mirror array and the electrostatic field used for its actuation is simulated. The simulation is then used to study the phenomenon of pull-in and its optimization. Then, a homogenized model for the electrostatic field in the vacuum space surrounding in the micro-mirror array has been built using an asymptotic method. The contributions to the development of MEMSALab consist in the introduction of an extension and combination theory that will be used to construct multiscale models based on various asymptotic approaches by a process of successive complexifications. Finally, a complete specification language for using MEMSALab is presented and illustrated by significant examples. In particular, it was used to encode the derivation of a homogenized model that serves as an initial state to the extension-combination method

Miniaturization of optical devices is increasingly needed in optical communication, imaging, and instrumentation. In the recent years, micro optics using MEMS techniques has been gradually playing an important role. The thesis first presents a novel addressable corner micromirror array for wide free-space optical applications. The corner mirror, composed of two mutually orthogonal reflective surfaces, may reflect incident light beam at any angle back of one specific plane to its incoming direction. Each micromachined corner mirror is constituted by three elements: a vertical mirror, a movable horizontal mirror, and a bottom electrode. In microfabrication, the bulk micromachining is used to fabricate all three opto-mechanical elements that bulk material of single crystal silicon provides superior opto-mechanical properties of polished surface, flatness and low residual stress. Meanwhile, the vertical mirrors are anisotropically bulk-micromachined with a (110) Si wafer for virtually vertical planes while the horizontal movable mirror plates and bottom electrodes are made with Si (100) wafers. In this report an array of micromachined corner mirrors is first reported to manipulate light beam in free space, equivalent to an optical function of lens and mirror integration. In addition, the corner micromirror allows to provide actuation on one of the reflective planes at each corner mirror, causing destruction of preset orthogonal planes. Incorporated with a grating and other optical components, the new device may provide simultaneous wavelength selection in free space and switching function for wavelength as well as intensity. In such an appropriate optical system, the corner micromirror may alleviate alignment problems and simplify assembly procedure. As experimentally achieved, the corner micromirror array may have the potential on an external-cavity tunable semiconductor laser, optical add/drop multiplexing, dual wavelength of interferometry or other applications.

In this dissertation, we present several types of light extraction enhancement structures on the backside of light emitting diodes (LEDs) to enhance the efficiency of light output. The first one is auto-cloned photonics crystal (APhC) on the backside of the sapphire wafer of the LED substrate, and the second one is micro mirror array (MMA) structure which was embedded in the gallium nitride (GaN) LED mainbody by the fabrication process of epitaxial lateral overgrowth (ELOG). The first section of the dissertation is related to research of the APhC. Based on the theory of thin film growth, we simulated the growth of the auto-cloned Ta2O5/SiO2 multi-layer photonic crystal with a lateral saw-tooth period under the mechanism of deposition and etching. Ion-beam-sputter (IBS) was applied to deposit the films and RF-bias etching was applied simultaneously with the IBS on the Ta2O5 film. Both simulation and experiment results showed that the quality of the auto cloning can be optimized and well controlled by the RF-bias power. There exists an intermediate power range, within this range, the drop of peak to valley height variation of the saw-tooth profile can be reduced significantly to achieve high degree of auto-cloning. Analysis showed that simultaneous deposition and etching at the proper RF-bias power on the Ta2O5 has the capability to compensate the flattening effect of the SiO2 deposition such that the saw-tooth surface profile can be maintained. In the second section of the dissertation, we introduce the fabrication of three dimensional (3-D) APhC of Ta2O5/SiO2 multi-layers on the backside of the sapphire wafer that has InGaN/GaN multi-quantum wells (MQWs) LED on the front side. 94% light extraction enhancement in comparison to the LED without APhC was obtained. Electrical properties of the LED did not affected by the APhC and its fabrication process. Experimental evidences showed that light extraction enhancement mechanism is in two aspects: for rays that are emitted from the source and incident at lower angle of incidence to the APhC, the APhC acts as a high reflector; for rays incident at higher angle of incidence to the APhC, first order diffracted light from the APhC appears, the diffracted light is concentrated around the surface normal and is therefore capable of escaping. In the third section of the dissertation, we propose a light extraction enhancement structure by using the heat-resistive dielectric MMA embedding in the ELOG GaN. Taking advantages of reducing dislocation density by ELOG together with the capability of diffraction and high reflectance of the patterned structure from the MMA, higher light output power for the LED can be expected. The MMA of Ta2O5/SiO2 dielectric multi-layer with the mirror diameter of 3?慆 and the array period of 6?慆 was fabricated on c-plane sapphire substrate. ELOG of GaN was applied to the MMA that was deposited on both sapphire and sapphire with 2.56?慆 GaN template. The MMA was subjected to 1200oC high temperature annealing and remained intact with high reflectance in contrast to the continuous multi-layer for which the layers have undergone severe damage by 1200oC annealing. The result implies that our MMA is compatible to the high temperature MOCVD growth environment of GaN. In the final section of the dissertation, we propose fabrication of MQWs InGaN/GaN LEDs, 300?慆 ?e 300?慆 chip size, with Ta2O5/SiO2 dielectric multi-layer MMA embedded in the ELOG GaN on the c-plane sapphire substrate. MQWs InGaN/GaN LEDs with ELOG embedded patterned SiO2 array (P-SiO2) of the same dimension as the MMA were also fabricated for comparison. Dislocation density was reduced for the ELOG samples. 75.2% light extraction enhancement for P-SiO2-LED and 102.6% light extraction enhancement for the MMA-LED were obtained over the standard LED. We demonstrated that the trapped lights can be redirected from the MMA by multiple-diffraction to escape from the LED. Therefore, the light extraction can be enhanced.

A maskless lithography system is developed which can generate any arbitrary patterns. The system consists of an illumination system, a digital micro mirrors devices (DMD), and a projection system including an achromatic lens pair and a double-sided micro lens and spatial filter array (D-MSFA). The DMD plays as a virtual mask, which can generate any arbitrary patterns by individually turning on or off each micro mirror. The achromatic lens pair projects image of each DMD’s mirror onto the first lens of D-MSFA. The D-MSFA consists of 2 micro lens arrays and a pinholes array which is located at the focal plane of the first micro lens array. The first micro lens array(MLA1) focus the light from DMD to its corresponding pinhole, the second micro lens array( MLA2) then projects image of pinholes array onto substrate to form a points array of light. The substrate is carried by a XY stage, software is developed to synchronize the XY stage moving with DMD. The profile of microlens is design and optimized by a software namely Zemax optics studio to a chieve smallest focused spot size. A technique has been developed to fabricate a large area D-MSFA, which ensures the high accuracy profile and alignment between micro lens arrays and pinhole array. After fabrication, D-MSFA achieves 10μm UV spot sizes at FHMW level. Finally, this study successfully generate arbitrary patterns with the minimum line width is 5 μm.

Повний текст джерелаRäumliche Lichtmodulatoren (Spatial Light Modulators, SLMs) auf Basis von Mikro-Opto-Elektro-Mechanischen Systemen (MOEMS) finden zunehmend Anwendung in verschiedensten Teilgebieten der Optik und ermöglichen neuartige Funktionalitäten. Die Technik ermöglicht Frameraten von einigen kHz bis in den MHz-Bereich sowie Auflösungen bis in den Megapixelbereich. Der Fachbereich macht nach wie vor rasche Fortschritte, technologische Weiterentwicklungen sind aber stets mit hohem Aufwand verbunden. Vor diesem Hintergrund widmet sich diese Arbeit der Frage: Welchen Beitrag kann optisches Systemdesign zur Weiterentwicklung der MOEMS-SLM-basierten Modulation leisten? Bereits eine Linse stellt ein Beispiel für ein optisches System dar. Diese Dissertation beschäftigt sich mit Systemdesign auf Basis der Fourier-Optik, bei der die Welleneigenschaften des Lichts genutzt werden. Auf dieser Basis können Arrays von Mikrospiegeln die flächige Verteilung von Licht einstellen. Beispielsweise können Kippspiegel die Intensitätsverteilung in einer Bildebene steuern. In dieser Dissertation werden Variationen der dafür nötigen Apertur untersucht. Neben bekannten absorbierenden Blenden werden insbesondere Phasenfilter untersucht, welche eine flächig verteilte Verzögerungswirkung auf die Lichtwelle aufbringen. Diese Dissertation schlägt die Kombination von MOEMS-SLMs mit statischen, pixelierten Elementen im selben System vor. Hierbei kann es sich um pixelierte Phasenmasken handeln, auch bekannt als diffraktive optische Elemente (DOEs). Analog existieren pixelierte Polarisatorarrays und absorbierende Fotomasken. Die Kombination von SLMs und statischen Elementen ermöglicht neue Freiheiten im Systemdesign. Diese Arbeit schlägt neue Modulationssysteme auf Basis von MOEMS-Kippspiegel-SLMs vor. Diese Systeme nutzen analoge Kippspiegelarrays für die simultane Modulation von Intensität und Phase sowie von Intensität und Polarisation. Die vorgeschlagenen Systeme eröffnen damit neue Möglichkeiten für die MOEMS-basierte Flächenlichtmodulation. Ihre Eigenschaften werden mithilfe von numerischen Simulationen validiert und untersucht. Aus diesen Nah- und Fernfeldsimulationen werden Systemeigenschaften und Limitierungen abgeleitet. Es wird in dieser Arbeit gezeigt, dass die Modulation verschiedener MOEMS-SLM-Typen auf Basis des Systementwurfs fundamental verändert werden kann. Senkspiegelarrays werden klassischerweise zur Modulation der Phase eingesetzt und Kippspiegelarrays zur Modulation der Intensität. Diese Arbeit schlägt die Nutzung von Subpixel-Phasenstrukturen vor. Diese verleihen Kippspiegeln näherungsweise die phasenmodulierende Wirkung von Senkspiegeln. Um dies zu erreichen, wird ein neuartiges Optimierungsverfahren vorgestellt. Senkspiegelarrays sind nur in geringem Umfang verfügbar. Im Gegensatz dazu sind Kippspiegelarrays gut etabliert. In Kombination mit Subpixel-Phasenstrukturen könnten Kippspiegel in einigen Anwendungen Senkspiegel ersetzen. Diese und andere Herausforderungen der MOEMS-SLM-Technologie lassen sich auf der Grundlage des Systemdesigns adäquat adressieren.
