Ultralow-loss integrated photonics enables bright, narrow-band, photon-pair sources
Ruiyang Chen, Yi-Han Luo, Jinbao Long +3
Photon-pair sources are critical building blocks for photonic quantum systems. Leveraging Kerr nonlinearity and cavity-enhanced spontaneous four-wave mixing, chip-scale photon-pair…
