Abstract: An optical homodyne differential phase
shift keying (DPSK) receiver for receiving and demodulating optical
input signals, is provided with a power splitter for splitting the
input signal into first and second signals, a delay is applied to
the second signal, an optical amplifier optically amplifies the
delayed second signal, and a balanced noise reduction circuit
combines the first signal and the delayed amplified second signal to
produce a demodulated output signal. |
