Research and Development of Monolithic Photodetector Integrated Circuit for Optical Disc Signal Pickup

Abstract

PDIC(PhotodetectorIntegratedCircuit)是光盘存储系统光学头的关键元件之一,由于其巨大的应用市场和在光电集成电路(OEIC)领域潜在的科研价值,目前已经成为硅基OEIC研究的一个热点。相比混合集成,单片集成OEIC降低了器件互连距离,最大限度地消除各种寄生参量的影响,大大提高了器件的工作频率,更具有小体积、低成本、高可靠性等优势,是实现PDIC高性能、低成本的根本出路。 虽然全球90%的光学头生产厂商都在中国大陆,但PDIC元件都依靠进口。近年来我国逐步认识到PDIC的重要性,相关单位也曾致力于PDIC的研制,但目前尚未见到有自主知识产权的单片集成PDIC产品...PDIC (Photodetector Integrated Circuit) is one of the key elements in optical pickup unit (OPU) of optical storage systems. It has attracted great attention in Silicon OEIC study due to the huge application market and the potential scientific research value in OEIC field. Comparing with hybrid solution, monolithic OEIC provides more advantages, such as compactness, high bandwidth, low-cost, high r...学位:理学博士院系专业:物理与机电工程学院物理学系_凝聚态物理学号:B20032400
