Photonic-Chip-Based Femtosecond Pulse Generator

We realize an electro-optic time lens on a lithium niobate photonic chip. By temporally carving a continuous-wave single-frequency laser, we generate a flat-top comb spectrum with 10.5-nm bandwidth and a 30-GHz pulse train with 532-fs duration. (c) 2021 The Author(s)
