Semiconductor quantum well membranes for tunable coherent waveguide laser arrays
Semiconductor quantum well membranes for tunable coherent waveguide laser arrays
We present coherent laser arrays in a silicon photonics compatible waveguide geometry in optically pumped semiconductor membrane quantum well lasers (MQWLs) on oxidised silicon and silicon carbide substrates. Real and reciprocal space imaging is used to investigate the emission of the laser arrays and mutual coherence is seen to be maintained while operating on single and multiple longitudinal modes in each cavity. Further, we investigate writing laser cavity arrays through micro-structuring of the MQWL and also through the utilisation of a spatial light modulator (SLM) to define areas of gain in the MQWL by shaping the pump beam.

Abstract
We present coherent laser arrays in a silicon photonics compatible waveguide geometry in optically pumped semiconductor membrane quantum well lasers (MQWLs) on oxidised silicon and silicon carbide substrates. Real and reciprocal space imaging is used to investigate the emission of the laser arrays and mutual coherence is seen to be maintained while operating on single and multiple longitudinal modes in each cavity. Further, we investigate writing laser cavity arrays through micro-structuring of the MQWL and also through the utilisation of a spatial light modulator (SLM) to define areas of gain in the MQWL by shaping the pump beam.
