HIGH SPEED CHAOS OPTICAL SIGNAL GENERATION OPTICAL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To generate random numbers with high disorder that is capable of simplifying an entire system, and can cope with a request for generating a high-speed random number.SOLUTION: A high-speed chaos optical signal generation optical circuit is configured to: demultiplex, by an optical demultiplexer SP-1, RZ type clock signal light to be output from a light output port P-MZ-1-cross of a Mach-Zehnder interference type light intensity modulation part MZ-1 into two systems; input the RZ type clock signal light of two systems to phase modulators R1 and L1 provided one by one in two interference arms in the Mach-Zehnder interference type light intensity modulation part MZ-1 as clock signal light for controlling a phase modulation; and thereby generate a phase difference in RZ type clock signal light to be input from a light input port P-MZ-1-1 and propagating in the two interference arms. The optical demultiplexer SP-1 is capable of adjusting a demultiplex rate in accordance with a signal from an outside.
