Optical receiver

An optical receiver comprising:

• an optical divider that divides an optical input signal into a plurality of paths;
• a plurality of optical-to-electrical converters that respectively converts the divided optical input signals into electrical signals;
• a plurality of discriminators that respectively outputs discrimination results by discriminating the electrical signals output from the optical-to-electrical converters based on predetermined thresholds;
• and
• an operational circuit that performs a predetermined logical operation with the discrimination results output from the discriminators.

An optical communication system comprising:

• an optical transmitter that transmits an optical signal;
• and
• an optical receiver that receives the optical signal transmitted from the optical transmitter, wherein
• the optical receiver includes
• an optical divider that divides the received optical signal into a plurality of paths;
• a plurality of optical-to-electrical converters that respectively converts the divided optical imput signals into electrical signals;
• a plurality of discriminators that respectively outputs discrimination results by discriminating the electrical signals output from the optical-to-electrical converters based on predetermined thresholds;
• and
• an operational circuit that performs a predetermined logical operation with the discrimination results output from the discriminators.
