Rainbows on demand: coherent comb sources on a photonic chip

该项目旨在创造光子电路技术，从单个芯片产生数百条相干激光线。新兴的工业可扩展的薄膜铌酸锂平台上的氮化硅将被推进到具有前所未有的效率和创新的监测和控制技术的谐振调制器和非线性波导。当组合在一起时，这些组件将使高度灵活和强大的系统产生梳状的相干激光线。这些光子芯片梳状源价格低廉、结构紧凑且节能，对光谱学、显微镜、精密测量、量子计算和超快速光纤通信具有变革性影响。

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.
