Reconfigurable fiber-to-waveguide coupling module enabled by phase-change material incorporated switchable directional couplers
Abstract In silicon photonics, grating-assisted fiber-to-waveguide couplers provide out-of-plane coupling to facilitate wafer-level testing; however, their limited bandwidth and efficiency restrict their use in broadband applications. Alternatively, end-fire couplers overcome these constraints but r...
