Microresonators offer a simpler approach to sensing with light pulses

Science Daily  October 1, 2018 An international team of researchers (Switzerland, Russia) has developed a simpler method to generate multiple frequency combs using optical microresonators consisting of a crystalline disk a few millimeters in diameter. At every round, a part of the soliton exits the resonator, producing a stream of optical pulses. It allows the light to travel in the disk in spatial modes of the resonator. In this way, they were able to generate up to three frequency combs at the same time. Using multiplexing scheme, the team demonstrated several applications, such as dual-comb spectroscopy, and rapid optical sampling…read […]
