Patent ID: 8184667

Claim:
An electro-optic (EO) Bragg deflector, comprising: an EO crystal with one of a 1D and a 2D spatially modulated EO coefficients, having an ordinary refractive index, an extraordinary refractive index and a refractive-index change, Δn o,e , governed by an expression: Δn o,e =−(½)n 3 o,e r 13,33 E z s(x), where E z is an electric field applied along a crystallographic z direction of the EO crystal, n o and n e are the ordinary and the extraordinary refractive indices without the applied electric field, respectively, r 33 and r 13 are relevant Pockels coefficients for an ordinary incidence wave and an extraordinary incidence wave, respectively, and s(x)=±1 and denotes a sign of a crystal-domain orientation of the EO crystal as a periodic function of a crystallographic x direction; a set of electrodes on the crystal; and a voltage driver connected to the set of electrodes.
