9414557 Lu This proposal addresses the design and fabrication of polarization and phase sensitive normal incidence multiple quantum well light modulator array. The device is based on the anisotropic excitonic and concomitant light polarization rotation to achieve high contrast ratios. The anisotropic excitonic absorption and birefringence are created by the in-plane anisotropic strain in multiple quantum well structures. The modulator utilizes the quantum confined stark effect (QCSE) to electrically tune the phase retardation and polarization rotation. This proposal represents a two-year collaboration project between the Microelectronics Research Laboratory (MERL) at Rutgers University and the Electronics and Power Sources Directorate (EPSD) of the Army Research Laboratory. We Have been working closely at the preliminary stage of the project, and have demonstrated the single modulator device based on electrically tunable polarization rotation and phase retardation in uniaxially strained (100) MQW, which exhibits an exceedingly high contrast ratio of 5000:1. The proposed work will further develop the modulator array (at least 4x4) to demonstrate its capability as a spatial light modulator. The work at Rutgers will focus on processing development, structural characterization, and theoretical modeling. In addition, a graduate student from Rutgers will spend a majority of his time at EPSD, performing the optical studies for this project. The National Science Foundation's support will greatly enhance our joint efforts in this area. ***

该方案涉及偏振和相敏垂直入射多量子阱光调制器阵列的设计和制造。 该器件基于各向异性激子和伴随的光偏振旋转来实现高对比度。 在多量子阱结构中，各向异性激子吸收和双折射是由面内各向异性应变引起的。 该调制器利用量子限制斯塔克效应（QCSE）来电调谐相位延迟和偏振旋转。 该提案代表了罗格斯大学微电子研究实验室（MERL）和陆军研究实验室电子和电源理事会（EPSD）之间为期两年的合作项目。 我们一直在密切合作，在项目的初步阶段，并展示了单调制器设备的基础上，电可调的偏振旋转和相位延迟在单轴应变（100）MQW，表现出非常高的对比度为5000：1。 拟议的工作将进一步开发调制器阵列（至少4x4），以证明其作为空间光调制器的能力。 在罗格斯大学的工作将集中在加工开发，结构表征和理论建模。 此外，罗格斯大学的一名研究生将在EPSD度过他的大部分时间，为这个项目进行光学研究。 国家科学基金会的支持将大大加强我们在这一领域的共同努力。 ***
