Original abstract
Rubidium titanyl phosphate (RTP) is widely used in bulk Pockels cells because it combines a useful linear electro-optic response with low dielectric permittivity, high electrical resistivity, negligible piezoelectric ringing, and high optical-damage tolerance. Its use in integrated or guided-wave modulators has been limited by the absence of a mature thin-film RTP platform. Here we propose a dielectric-loaded guided-wave modulator in which a silicon nitride strip on an unetched bulk RTP crystal forms a near-surface optical mode that overlaps with side-electrode fields. The analysis focuses on full-vector optical modes, GSG electrostatic and RF response, tensor-aware electro-optic coupling, and device-level performance at 1064~nm.
