Title:
METHOD FOR RECEIVING SIGNAL IN WIRELESS OPTICAL COMMUNICATION SYSTEM, AND RECEIVING TERMINAL THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/090962
Kind Code:
A1
Abstract:
Proposed is a receiving terminal for receiving a signal in wireless optical communication, according to the present disclosure. The receiving terminal may include: a transceiver for receiving an optical signal of an orbital angular momentum (OAM) mode from a transmitting terminal; a demodulator composed of at least one phase shifter; a photoelectricity converter composed of at least one photodiode; and a processor connected to the transceiver, the demodulator, and the photoelectricity converter. In addition, the at least one phase shifter may convert an optical signal of the OAM mode into an optical signal of a Gaussian mode, and the at least one photodiode may convert an optical signal of the Gaussian mode into an electrical signal.
