A compact, single-etch silicon photonics waveguide crossing based on low quality factor cavity and optimized by a genetic algorithm is demonstrated. The device has 0.1~0.3 dB insertion loss and < -35 dB crosstalk per crossing for fundamental TE mode in the 1550-1600 nm wavelength band, with a footprint of 5 x 5 {\mu}m$^2$. 
Inverse-Design-based Light Via for Multi-Layer Photonic Integration Circuit
A multi-layer light via for TE-polarized light is proposed based on inverse design. Simulation results show that the insertion loss is 0.55dB at 1550nm, and the device has an ultra-wide 1dB bandwidthExpand
