Waveguide Array for High Density Integration with Low Crosstalk Top: Average transmission of each waveguide output port (indicated by color)Invention Summary:The success of silicon photonic devices depends on high integration density. However, at the sub-wavelength scale, waveguides suffer from high crosstalk.The present technology reduces crosstalk at the sub-micron scale by using a superlattice of waveguides....

Parallel-coupled Dual Racetrack Silicon Micro-resonators for Quadrature Amplitude Modulation Left: Schematic of parallel-coupled dual racetrack resonators. Ein and Eout are the input and output fields of the central waveguide. Right: Simulated intensity variations as the refractive index (Δn) of the waveguides in the top and bottom racetracks are modulated.Invention Summary:A parallel-coupled dual racetrack micro-resonator structure has...
