CW Tunable Laser - Butterfly Package
The Finisar S7500 tunable laser incorporates a monolithic InP chip that integrates a tunable MG-Y laser with a semiconductor optical amplifier (SOA). The MG-Y (Modulated Grating Y-branch) laser is an electronically tuned device that can address any wavelength in the C-band. Since no mechanical or thermal adjustments are necessary, channel switching is very fast. The SOA facilitates flexible control of the output power and acts as a shutter when reverse biased, enabling dark tuning between channels. The devices are packaged into a compact, low-profile hermetically sealed package, with an internal optical isolator and a wavelength locker.
