Reprogrammable optical phase array.

A novel reprogrammable optical phase array (ROPA) device is presented as a reconfigurable electro-optic element. One specific application of the ROPA, a 1 x 6 electro-optic space switch, is fully described. Switching angles are within 2 degrees , and switching is achieved through a complementary metal-oxide semiconductor (CMOS) controlled, diffraction based, optical phase array in a bulk BaTiO3 crystal.

Bulk electro-optic deflector-based switches.

We propose two novel electro-optic (EO) deflectors based on two new nonrectangular geometries: the parabolic and the half-horn configurations. These devices not only provide excellent deflection angles, but also have the potential to build nonblocking 2 x 2 optical switches. A deflector figure of merit is defined, and comparisons with existing EO deflectors are given.
