Dual-wavelength AlInGaAs-InP grating-outcoupled surface-emitting laser with an integrated two-dimensional photonic lattice outcoupler

Grating-outcoupled surface-emitting semiconductor lasers emitting two independent wavelengths separated by 9.5 nm from a common aperture in a monolithic crossed configuration is demonstrated. This configuration provides integrated wavelength multiplexing at /spl sim/1300 nm from a single aperture into a single fiber, simplifying packaging and reducing cost.
