On-chip optical spectrometer with a tunable micro-ring resonator and a Mach-Zehnder interferometer lattice filter
{{output}}
We propose and demonstrate a compact on-chip optical spectrometer by integrating a tunable micro-ring resonator (MRR) with a 4-channel wavelength demultiplexer (DEMUX) based on a Mach-Zehnder interferometer (MZI) lattice filter. The MRR with a 3-dB bandwidth o... ...
