| 2 | Spatio-temporal isolator in lithium niobate on insulator显示文摘In this contribution,we simulate,design,and experimentally demonstrate an integrated optical isolator based on spatiotemporal modulation in the thin-film lithium niobate on an insulator waveguide platform.We used two cascaded travelling wave phase modulators for spatiotemporal modulation and a racetrack resonator as a wavelength filter to suppress the sidebands of the reverse propagating light.This enabled us to achieve an isolation of 27 dB.The demonstrated suppression of the reverse propagating light makes such isolators suitable for the integration with III-V laser diodes and Erbium doped gain sections in the thin-film lithium niobate on the insulator waveguide platform. | Haijin Huang Armandas Balčytis Aditya Dubey Andreas Boes Thach GNguyen Guanghui Ren Mengxi Tan Arnan Mitchell | 2023 | Opto-Electronic Science2023，2，3： | 0 |
