Near-infrared self-written waveguide spot size converter for single- and multichannel fiber-to-chip self-coupling

Near-infrared (NIR) light-induced self-written (LISW) optical waveguide technology provides passive alignment between telecommunications and silicon photonic devices and offers high-throughput and self-alignment advantages. Although fiber-to-chip self-coupling based on the NIR LI...
