High performance waveguide devices for next generation photonic chips

SPIM-WGs with varying cross-sections, enabling mode conversion. Credit: Bangshan Sun One of the most important elements in photonic chips or quantum chips is the optical waveguide. However, due to limitations in existing fabrication methods, it is tricky to efficiently produce waveguides with high precision control of the 3D cross-section shape and size. To resolve this … Read more
