Abstract :
In summary, we have demonstrated for the first time polarization insensitive mixed strain InGaAsP quantum well laser amplifiers with monolithically integrated mode transformers and show experimentally that an integrated laterally taper section not only provides better coupling of the mode to single mode fiber but maintains the polarization insensitivity of the active region design. In addition, we have achieved the desired mode transformation while maintaining high gain (18 dB) and high saturation power (10 dBm)
