ABSTRACT:
The feedback control loop for temperature stabilization of a tunable diode laser consists of a series of lenses or gratings and a detector array disposed in the optical path. The lenses or gratings of the feedback loop are formed in a planar optical waveguide which is temperature stabilized, being fabricated from a plurality of dielectric materials which have approximately equal and opposite changes in refractive index with temperature. Light from a tunable diode laser is input into the loop and is collimated, deflected, and focused onto a portion of the detector array depending on the wavelength of the light. Each detector within the array corresponds to a given wavelength. The detector converts the detected wavelength into an electrical signal which is fed back to the laser phase control to provide tuning to the desired channel.
