共振腔发光二极管(RCLED)是一种新型发光二极管(LED)结构,同时具备了传统LED和垂直腔面激光器(VCSEL)两者的优点,具有良好的应用价值和广阔的市场前景。介绍了RCLED的基本原理和结构,以及器件结构的设计要点,指出发射波长650nm的RCLED在塑料光纤(POF)通信领域的应用优势,可以作为民用数据通讯系统用光发射器件的首选。对近年来RCLED尤其是红光波长范围的RCLED发展情况进行了概述,同时指出我国在这一领域的研究现状。
Resonator Light Emitting Diode (RCLED) is a new type of light emitting diode (LED) structure with the advantages of both traditional LED and vertical cavity surface laser (VCSEL), and has good application value and broad market prospects. The basic principle and structure of RCLED and the design points of the device structure are introduced. The application advantages of RCLED with 650nm emission wavelength in plastic optical fiber (POF) communication are pointed out. It can be used as the first choice of light emitting device in civil data communication system. In recent years, RCLED especially the development of RCLED in the wavelength range of red light are summarized, and the research status of our country in this area is also pointed out.
