Abstract

An on-chip integrated wavelength filter and router device is realized using two-dimensional metal/dielectric nanostructures. The device can filter wavelengths of light from an incident broadband beam, and further route the filtered signals to different ports on the same chip. The footprint of the entire device is only 3.4 μm × 7.3 μm. Both the number of wavelength channels and the central wavelength of each channel can be tuned by adjusting the structure parameters, or by using a pumped laser. This work demonstrates an ultracompact and robust integrated multifunctional device, and provides a novel and flexible method for the integration of nanophotonic devices.
