ABSTRACT:
An integrated frequency conversion and scanner for converting the frequency of an input light beam and deflecting the converted light beam through an electronically controlled angle is disclosed. This structure includes an electrooptic crystal including a region formed for converting the frequency of the input light to a higher frequency; and a field changing structure associated with selected regions of the crystal arranged so that an electric field is created at least partially within the crystal to change its refractive index to thereby deflect the converted light beam through an electronically controlled angle.
