  • Systems, methods, and apparatuses for optically pumped vertical cavity surface emitting laser devices
    Patent number: 6940885
    Abstract: Monolithic integrated vertical-cavity surface-emitting laser devices are disclosed including an edge-emitting semiconductor pump laser (PL), an optically-pumped vertical-cavity surface-emitting laser (VCSEL), and a means for deflecting and shaping the output beam of the pump laser to optically excite the VCSEL. The optically-pumped VCSEL structure may be adapted to include a resonant cavity with multiple fixed wavelengths, or a resonance cavity whose wavelength is continuously tunable. Wafer level manufacturing techniques are also disclosed.
