Abstract

We report on novel architectures of the hybrid master oscillator power amplifier (MOPA) assemblies incorporating vertically stacked surface-emitting laser diodes. Optical coupling between the MO and the PA is provided by nonresonant grating couplers integrated on both of the devices. The MOPA consists of a MO chip with dual grating reflector for single wavelength operation and a flared PA chip with two grating outcouplers. Optical peak power over 100W and spectral bandwidth of 0.2nm were achieved from the single MOPA while the MO operated in the gain-switching regime and the PA operated as a traveling wave amplifier. New designs of coherent MOPA arrays are proposed based on a phase locked MO bar and a single transverse mode PA bar. This MOPA assembly requires an optical cross-coupling between the bars provided by tilted gratings which have been developed and experimentally evaluated.
