Research Topics


Currently, achieving higher modulation rate at lower optical loss is the major technology issue to meet the operational requirements for practical implantation of advanced modulated corner cube concept for numerous military laser communication applications of both ground and space. To substantially increase the modulation rate beyond that of the available liquid crystal technologies, an alternate modulation technology must be developed. Optoceramics hold promise to produce leading edge retro-modulators. In the phase I program, NZ Applied Technologies have demonstrated a solid-state electro-optic retro-modulator that has fast response (16dB) and low optic insertion loss (5Mbs), low optical insertion loss (20dB), large clear aperture (2"x2"), broadband (500nm ~ 2000nm light), moderate energy consumption, and cost effectiveness.
