Patent ID: 7075955

Claim:
An integrated optical parametric oscillator: an input face being anti-reflective to an incident pump beam; an optical-parametric-oscillation region along an optical path of the pump beam, the optical-parametric-oscillation region being operative to convert the pump beam into a signal beam and an idler beam, wherein the input face is reflective to the signal beam and the idler beam; a grating along an optical path of the signal beam and the idler beam converted by the optical-parametric-oscillation region, the grating being operative to diffract at least a portion of the signal beam; a reflecting plane positioned along an optical path of the signal beam diffracted by the grating, wherein the reflecting plane is reflective to the signal beam; an ultra-fine-steering region between the reflecting plane and the grating, the ultra-fine-steering region being operative to steer the optical path of the signal beam diffracted from the grating; and an output face along an optical path of the signal beam reflected from the grating, the output face being reflective to the pump beam and the idler beam and partially transmissive to the signal beam.
