Latest Patents

Yeyu Tong holds a patent for a multimode waveguide grating coupler. This invention describes a high coupling-efficiency waveguide grating coupler designed for use in the optical interface between a planar multimode waveguide and a multimode optical fiber. The coupler facilitates mode division multiplexed optical communication systems by launching light from different modes of the planar waveguide into the various modes of the multimode optical fiber and vice versa. The silicon-based multimode waveguide grating coupler was utilized to couple two polarizations of a multimode silicon waveguide into the LP01 mode and LP11 mode from a step index multi-mode fiber (MMF). Preliminary design simulations predicted a coupling efficiency of -4.3 dB for the LP01 mode and -5.0 dB for the LP11 mode. Experimental results showed coupling efficiencies of -4.9 dB and -6.1 dB for LP01 and LP11 modes, respectively.
