Paper Abstract

Observation of spatial hole burning reduction is reported for the first time to our knowledge on flared 1480nm high power InGaAsP/InP buried ridge lasers. We determined the longitudinal carrier density profile by spatially resolved spontaneous emission measurements for slightly tapered and straight active waveguides. The tapered stripe shows spatial hole burning reduction leading to 25% output power enhancement.
