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 compliant
per RoHS Directive 2011/65/EU ¹.
