Multi‐Wavelength Quantum Light Sources on Silicon Nitride Micro‐Ring Chip

Multi‐Wavelength Quantum Light Sources on Silicon Nitride Micro‐Ring Chip Abstract Multi‐wavelength quantum light sources are extremely desired in establishing communication links among multiple users for realizing quantum networks. Despite recent impressive advances, developing such a quantum light source with high quality remains challenging. Here a multi‐wavelength quantum light source using a silicon nitride micro‐ring with a free spectral range of 200 GHz is demonstrated. The generation of...
