    We report on development of the mid-infrared antimonide based laser technology targeting dual wavelength operation for intra-cavity difference frequency generation. The devices utilize Y-branch architecture with high order DBR reflectors controlling the laser emission spectrum. The device active region contain asymmetric tunnel coupled quantum well with built in resonant second order nonlinearity. The epitaxially regrown photonic crystal surface emitting GaSb-based lasers will be demonstrated.

    The DBR diode lasers with asymmetric tunnel coupled quantum wells having built-in resonant second order nonlinearity were designed and fabricated. The devices can generate comparable power in two bands near 2 um separated by ~13 meV as required for intracavity difference frequency generation.
