Multilayer Silicon Nitride Based Coupler Integrated into a Silicon Photonics Platform with 0.5 dB Coupling Loss between Standard SMF and the As-Diced Chip Edge Facet

We experimentally demonstrate <0.5 dB coupling loss with <0.3 dB variation over the O-band for both polarizations between an integrated silicon photonics platform with an as-diced edge facet and butt-coupled standard single mode fiber.
