Study on photovoltaic effects of zn1-xcdxse znse multiple quantum wells 多量子阱光伏效应研究
In this dissertation, a novel m-z high speed modulator is proposed, analyzed, fabricated and measured, employing multiple quantum well ( mqw ) structures and traveling wave ( tw ) electrodes to meet the demand of low voltage and wide bandwidth 本论文采用行波量子阱结构来设计40ghz的电光调制器。为实现高带宽,低驱动的要求,本论文着重在量子阱的光学特性和器件的微波特性两个方面进行了深入的研究。
In this thesis, the basic operation in the optical computation was studied by analyzing the course of laser beams transmitting through a vmm, which is composed of an array of vertical cavity surface-emitting lasers, spherical and cylindrical lens, an array of multiple quantum well spatial light modulators and an array of the detectors 本文研究的光学矢量-矩阵乘法器主要是由垂直腔面发射激光器(vcsel)阵列、球面透镜和柱面透镜组、多量子阱空间光调制器(mqwslm)及ccd阵列构成。作为小尺寸的集成光学器件,必须要考虑衍射的作用。
