Patent ID: 7145714

Claim:
A method for poling ferroelectric crystal material to form one or more optical devices, comprising: defining a first optically effective region in a first predetermined portion of the ferroelectric crystal material at least in part with a first electrode segment; poling the first predetermined portion with a first poling voltage profile to establish a first domain aligned in a predetermined direction, the first domain having an edge that defines at least part of the first optically effective region, and the first poling voltage profile being optimized for the first predetermined portion; defining a second optically effective region in a second predetermined portion of the ferroelectric crystal material at least in part with a second electrode segment; and poling the second predetermined portion with a second poling voltage profile to establish a second domain aligned in a predetermined direction, the second domain having an edge that defines at least part of the second optically effective region, and the second poling voltage profile being optimized for the second predetermined portion.
