Abstract:
We propose and demonstrate the application of an intracavity horizontally tapered (in width) active stripe to adiabatically reduce the output beam divergence of a 1.48-μm InGaAsP/InP strained quantum well laser. We achieve far-field full width at half-maximum divergences as low as 13° together with 100 mW emitted power into stable single transverse mode and 400 mA driving current. Maximum coupling efficiency to lensed single mode fiber of 73% is obtained.
