Title:
SINGLE-PHOTON SOURCE DEVICE AND SINGLE-PHOTON EMISSION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/000316
Kind Code:
A1
Abstract:
A single-photon source device, comprising: a photonic crystal slab (101) and a photon conversion module (102). The photon conversion module (102) is coupled to the photonic crystal slab (101), and the photon conversion module (102) comprises a silicon carbide color center (1021) and an L3-type photonic crystal microcavity (1022), the silicon carbide color center (1021) being disposed in the L3-type photonic crystal microcavity (1022). The photonic crystal slab (101) has a first path (1011) and a second path (1012). The first path (1011) is used to receive pump light, and the photon conversion module (102) is used to convert the pump light into photoluminescence (PL) light. The second path (1012) is used to emit the PL light. A single-photon emission method and communication system can collect pump light and PL light in the same plane. Using the device to design or manufacture devices, such as an optical chip, effectively reduces the size of the devices and lowers integration difficulty, thereby improving functionality.
