Paper Abstract

Strain and thermal characterization of the cladding layer in InGaAs ridge waveguide (RWG) lasers is reported. We tune up a photoluminescence micro-probe technique for determining the temperature and strain profile of the cladding layer, in steps of ∼1μm, with a temperature resolution <1°K. A correlation between the facet temperature and type of protective coating is found. A correlation has been obtained between the facet temperature and the laser oscillating mode. The experimental strain profile is well reproduced by an inclined line-force model.
