Tunable shaping and switching of polychromatic light for integrated photonics

The recent advances in generation of multi-color light with supercontinuum spectrum could revolutionize numerous fields including optical sensing and characterization, spectroscopy, tomography, metrology, and telecommunications applications. However, traditional integrated photonics solutions were primarily designed for current optical fiber networks with narrow bandwidth, and they cannot be applied to the manipulation of light with ultra-broad spectrum. With this project, we aim to develop, and demonstrate experimentally, innovative concepts for tunable shaping and switching of polychromatic optical signals in compact integrated photonic devices, which will benefit leading edge fundamental science and emerging photonic industries.
