Tuning and Aging Characteristics of Multisectionwide Wavelength Tunable Semiconductor Lasers.

Abstract

This work involves design and construction of a 10-laser lifetime testbed that measures, under computer control different wavelength based characteristics at elevated temperatures overa period of 5000 hours. The objective is to quantify and analyze the various wavelength tuning aging characteristics of tunable semiconductor lasers: the Altitun GCSR And UCSBSGR (ONR funded), and identify physical aging mechanisms and relate back to fabrication. Our approach is to measure the wavelength characteristics of the tunable lasers using accelerated lifetime testing by maintaining the tunable laserat 650 C and automate the data collection of the characteristics over 5000 hrs.
