Exploring a Band-Edge Bragg Grating Modulator on a Hybrid Thin-Film Lithium Niobate Platform

In this work, we design, model, and characterize the Bragg grating modulator (BGM) on silicon-rich nitride and thin-film lithium niobate (SRN-TFLN) platform. In particular, the slow-light effect on the electro-optical modulation response is modeled and experimentally validated. The presented modulat...
