LN Wide Bandwidth Phase Modulator

LiNbO₃ wideband phase modulators employ microelectronics fabrication processes, utilizing either annealed proton exchange (APE) or Ti-diffusion waveguide technologies. Supporting both single-polarization and birefringent operation modes, these devices feature traveling-wave electrode configurations optimized for high-frequency performance across 1-30 GHz bandwidths. The modulators deliver exceptional reliability with robust temperature stability, maintaining consistent operation under extended thermal variations.
