A single photon source device includes a photonic crystal plate (101) and a photonic conversion module (102), in which the photonic conversion module (102) is coupled with the photonic crystal plate (101), and the photonic conversion module (102) includes a silicon carbide color center (1021) and a L3 photonic crystal microcavity (1022), and a silicon carbide color center (1021) is arranged in a L3 photonic crystal microcavity (1022); and a photonic crystal plate (101) has a first path. The path (1011) and the second path (1012); the first path (1011) are used to receive the pump light; the photon conversion module (102) is used to convert the pump light into photoluminescent PL; and the second path (1012) is used to emit PL light. A single photon emission method and communication system can collect pump light and PL light in the same plane. Using this device to design or manufacture optical chips and other devices can effectively reduce the size of devices, reduce the difficulty of integration, and thus enhance practicability.
