Chip-Based Lithium-Niobate Frequency Combs

Abstract

Lithium niobate is an excellent photonic material with large ${\chi }^2$ and ${\chi }^3$ nonlinearities. Recent breakthroughs in nanofabrication technology have enabled ultralow-loss nanophotonic devices based on a lithium-niobate-on-insulator (LNOI) platform. Here we present an overview of recent developments in the LNOI platform for on-chip optical frequency comb generation. These devices could lead to new opportunities for integrated nonlinear photonic devices for classical and quantum photonic applications.
