Finisar’s 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.
Description Finisar’s 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. The locker monitors both output power and frequency of the light emitted from the chip, enabling a closed loop control that guarantees stability of the frequency and output power over life, to within the requirements of 50 GHz ITU grid spacing applications. The S7500 is provided with polarization maintaining fiber for use with an external modulator. The laser is RoHS compliant and lead free per Directive 2011/65/EU.
