Microring resonator-assisted Fourier transform spectrometer with enhanced resolution and large bandwidth in single chip solution
Abstract
Here, the authors demonstrate a microring resonator-assisted Fourier-transform spectrometer, which is realized using a thermally tunable photonic Mach-Zehnder interferometer cascaded with a tunable microring resonator to enhance the resolution, all integrated with a photodetector onto a single chip.
