Study on photovoltaic effects of zn1-xcdxse znse multiple quantum wells 多量子阱光伏效應(yīng)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(jié)構(gòu)來設(shè)計40ghz的電光調(diào)制器。為實現(xiàn)高帶寬,低驅(qū)動的要求,本論文著重在量子阱的光學(xué)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(xué)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(diào)制器(mqwslm)及ccd陣列構(gòu)成。作為小尺寸的集成光學(xué)器件,必須要考慮衍射的作用。
