SKU: DSBR
The DSBR Series tunable laser source integrates multiple discrete Bragg reflector sections for coarse wavelength tuning, a phase section for fine and continuous tuning, and a semiconductor optical amplifier (SOA) for optical power amplification and control. It also includes an integrated shutter, which enables dark tuning when reverse-biased. This architecture allows for fast, precise wavelength control, making it ideal for dense wavelength division multiplexing (DWDM) and coherent optical communication, thanks to its wide tuning range, narrow linewidth, and rapid switching capability. The laser chip operates at a fixed temperature, eliminating slow thermal drift during tuning. Wavelength stability is maintained via an internal wavelength locker, which ensures accurate alignment to a 50 GHz or 100 GHz ITU grid. The wavelength locker also monitors front-facet output power, enabling feedback control to the SOA for stable operation. The device is supplied with polarization-maintaining fiber for compatibility with external modulators. The DSBR is mounted on a driver circuit board that features variable power control, shuttered tuning, trace tone, and stimulated Brillouin scattering (SBS) dither circuitry, all accessible via an RS-232 interface. Turn-key Benchtop is available with high optical power output up to 200mW.
