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...

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...
