Abstract
We report on the investigation of an optical M-by-N switch implementated as a photonic integrated circuit (PIC) in silicon on insulator. The switch relies on a star coupler for non-blocking routing of multiple optical signals. The latter are carried into and out of the star coupler in multi-core dielectric waveguides that support multiple modes. Routing is controlled by applying different optical-phase delays to the individual cores comprising the waveguide. We investigate theoretically and experimentally the viability of the architecture for routing optical signals in a PIC. In addition to signal routing, MASTR switch may be used for general matrix multiplication.
