Tuning and Aging Characteristics of Multi-Section Wide Wavelength Tunable Semiconductor Lasers
Abstract
This final report summarizes progress on analysis of wavelength tuning characteristics under accelerated aging lifetime measurements. This work involved design and construction of a 10-laser lifetime testbed that measures, under computer control, different wavelength based characteristics at elevated temperatures over a period of 5000 hours. A detailed static and dynamic model for simulation of GCSR lasers was developed and used to analyze lasers behavior. Objectives of this project were: To quantify and analyze the various wavelength tuning aging characteristics of Altitun GCSR tunable semiconductor lasers; To measure the wavelength characteristics of the tunable lasers using accelerated lifetime aging by maintaining the tunable laser at 50 and 65 deg C and automate the data collection of the characteristics over 5000 hrs. To identify physical aging mechanisms and relate them to fabrication, estimate realistic lifetime of devices, quantify and analyze various changes in output/tuning characteristics of devices, identify physical aging mechanisms and relate back to fabrication; and To develop an analytical model in order to study static and dynamic GCSR laser wavelength tuning, as well as switching times.
