Abstract
The 10-Gb/s directly modulated performance of InGaAsP RWG GC-DFB lasers is investigated up to 85 degreesC. At room temperature, devices have relaxatio n oscillation frequencies f(relax) greater than 20 GHz and damping Gamma gr eater than 100 GHz, f(relax) is greater than 6 GHz at 85 degreesC. Constant output power or extinction ratio are possible from 25 degreesC to 75 degre esC chip temperature, with open eyes observable up to 85 degreesC. Back-to- back transmission measurements in a Nortel Networks OC-192 system show erro r free transmission of a 2(23) - 1 pseudorandom bit sequence at 83 degreesC .
