4H-SiC Microring Chip Breaks Efficiency-Bandwidth Trade-off for Integrated Time-Bin Entangled Photon SourcesA 4H-silicon carbide microring resonator chip demonstrates high-rate time-bin entangled photon-pair generation while circumventing the canonical trade-off between generation efficiency and photon bandwidth in cavity-enhanced nonlinear sources. By engineering both the material non…
