【摘要】 基于LabVIEW虚拟仪器平台,研制了一套可调谐取样光栅分布布拉格反射式(Sampled Grating Distributed Bragg Reflector,SG-DBR)激光器的波长自动测试控制系统。该系统能对四段式SG-DBR激光器进行电流扫描,采集、分析其输出光谱,生成SG-DBR激光器的“波长-电流”数据查询表;并且通过调用数据查询表,实现对SG-DBR激光器输出波长的控制。更多还原

【Abstract】 By using LabVIEW virtual instrument technique,a wavelength auto-measurement and control system for Sampled Grating DBR(SG-DBR) lasers is developed.This system can automatically implement current scanning for SG-DBR laser,col-lect and analyze its output spectrum data,and generate its“wavelength-current”look-up table,by which the control of the out-put wavelength of the SG-DBR laser is realized.更多还原
