Nanophotonic Integrated Circuits

摘要

Luxtera's Phase I activities have yielded a large number of useful passive nanophotonic devices. The nanophotonic grating coupler and ring resonator are of particular importance. First, an update on the progress with these two components will be given, and then a description of an optimal system for leveraging these two components in the form of a multi-wavelength source will be described. Luxtera has developed these resonators in two configurations. First as a filter alongside a single waveguide, which provides a notch filtering function to the light passing through the waveguide. The second configuration is where the ring is placed between two waveguides, and on resonance light is dropped from one waveguide to the other. Luxtera proposes to use a variation of this second configuration to provide narrowband feedback to the active medium.
