Rainbows on demand: coherent comb sources on a photonic chip

点击翻译按钮获取中文摘要

This project aims to create photonic circuit technologies that will generate hundreds of coherent laser lines from a single chip. The emerging industrially scalable silicon nitride on thin-film lithium niobate platform will be advanced to create resonant modulators and nonlinear waveguides with unprecedented efficiency and innovative monitoring and control techniques. When combined, these components will enable highly flexible and robust systems for generating a comb of coherent laser lines. These photonic chip comb sources will be inexpensive, compact and energy efficient with transformative impact in spectroscopy, microscopy, precision measurement, quantum computing and ultra-fast optical fibre communications.
