摘要:

随着信息传递、处理以及存储能力要求的不断提升,传统的近红外通信波段已呈“容量紧缩”之势。而工艺与CMOS兼容、结构简单、成本低廉的硅基光电子技术在中红外信号传输和处理方面已经显示出独特优势,有望在中红外波段实现大规模集成,在非线性光学等领域实现新的飞跃。首先介绍了硅基光电子技术在中红外应用中的优势以及目前研究过程中所遇到的困难和挑战;其次结合材料属性和结构特性对一些基本元件(如波导、分束/合束器、二极管)等在中红外领域的最新研究成果进行了介绍;最后对近5年来在中红外波段所实现传感应用的非线性光学硅基器件(基于FWM的非线性光学器件、频率梳)和面向中红外通信应用的激光器、调制器、光电探测器进行了成果介绍,并对研究进展进行了总结。

Abstract:

“Capacity Crunch”in NIR field needs to be forestalled since the pressure of information transmission,processing and storage is continually growing.Silicon photonics,with compatibility of CMOS,compact structure and low fabrication cost,shows its superiority in the field of mid-IR transmission and signal processing.Thus a lead forward is excepted to be realized in large-scale integration of mid-IR devices and nonlinear optical and other field.The strengths and challenge of silicon photonics in mid-IR application were estimated firstly.Then some“building block”components of silicon photonics in mid-IR(waveguides,beam splitter/combiner,diode,etc)were introduced.Achievements of devices (nonlinear optical devices based on FWM,frequency comb in sensing field and laser,modulator,detector in communication field)within the last five years were presented.Finally,the conclusion was made for recent research progress.

Key words: silicon photonics, mid-infrared spectroscopy, nonlinear optical, sensing, optical communication
