Mode-Conversion-Based Chirped Bragg Gratings on Thin-Film Lithium Niobate
Photonics, 2022 In this work, we propose a mode-conversion-based chirped Bragg grating on thin-film lithium niobate (TFLN). The device is mainly composed of a 4.7-mm long chirped asymmetric Bragg grating and an adiabatic directional coupler (ADC).
