High performance 1.55 µm vertical external cavity surface emitting laser with broadband integrated dielectric-metal mirror

1.55 µm room-temperature continuous-wave operation of a high performance optically pumped vertical external cavity surface emitting laser is reported. The structure includes an active region with strain compensated quantum wells, and a broadband SiNx/Si/Au Bragg reflector transferred on an Si substrate by Au/In dry bonding. Output power of up to 45 mW is achieved at 0°C, and continuous-wave operation is observed up to 45°C.
