Abstract
An on-chip integrated nanobeam cavity array spectrometer (INAS) having an array of waveguide-coupled nanobeam cavities. Waveguide splitters are used to bring the signal from the input waveguide into each cavity. The spectrum of unknown input signal is obtained by collecting signal from each nanobeam cavity in the array.
