Study on photovoltaic effects of zn1 - xcdxse znse multiple quantum wells 多量子阱光伏效應研究
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 本論文采用行波量子阱結構來設計40ghz的電光調制器。為實現(xiàn)高帶寬,低驅動的要求,本論文著重在量子阱的光學特性和器件的微波特性兩個方面進行了深入的研究。
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 本文研究的光學矢量-矩陣乘法器主要是由垂直腔面發(fā)射激光器( vcsel )陣列、球面透鏡和柱面透鏡組、多量子阱空間光調制器( mqwslm )及ccd陣列構成。作為小尺寸的集成光學器件,必須要考慮衍射的作用。
