Abstract

By taking advantage of the recent advances in high quality sizable KTN crystal growth, a broadband large field of view (FOV) EO modulator is developed and presented in this paper. The experimental and theoretical studies indicate that the built EO modulator not only has a broad bandwidth (~1 GHz) but also has a large FOV (+/- 30 deg) because cubic phase KTN crystals do not introduce any intrinsic birefringence without applying the external electric field.
