为了在光开关器件的制作中实现低传输损耗的光波导,对InGaAs/InGaAsP分别限制异质结多量子阱(SCH-MQW)激光器结构进行了一系列带隙蓝移实验.将能量1~2MeV、注量1~5×1013 cm-2的P+注入到实验样品后,在700℃下快速热退火90s.发现光致发光谱的峰值位置发生蓝移9~89nm.蓝移量随着注入能量和注量的增大而增大,并且能量比注量对蓝移的影响更大.

A very successful technique that uses phosphorus ion implantation to enhance the interdiffusion of QW in InP based laser structure is described. The implanted ions create a large number of vacancies, which diffuse through the QW region upon annealing. The interdiffusion of both column Ⅲ and column Ⅴ atoms at the interface between barrier and QW layers takes place. Room-temperature photoluminescence (PL) spectra are obtained from the samples. PL emission peaks of the samples vary with dose and energy of implantation. PL spectrum are blue-shifted in wavelength from 9nm to 89nm. This reproducible technique of lateral band-gap control can be used in quantum-well photonics integrated circuits to produce low-loss waveguide.
