Y-cut LiNbO$_3$ 양자확산 광도파로를 이용한 전기광학 차단형 광변조기
Electro-Optic Cutoff Modulator on Y-cut LiNbO$_3$ Proton-Diffused Channel Waveguides
초록
The proton conserving effect of diffusion with self-aligned SiO2-cladding is investigated by infrared transmission spectra. Based on the proton conserving effect, proton-diffused channel waveguides with self-aligned SiO2-cladding substrates. And an electro-optic cutoff modulator with self aligned electrode that utilizes a single-mode proton-diffused channel waveguide in a Y-cut XX-propagating LiNbO3 substrate is fabricated. Over 20 dB extinction has been achieved with applied voltage of 15V.
