Abstract:
This disclosure provides systems, methods, and apparatus for mitigating the effects of interference signals on optical signals received at a direct-detection optical receivers. The optical receivers are capable of attenuating interference noise signals resulting from the interference between a transmitted optical signal transmitted from a transmitter to the optical receiver and one or more additional signals received at the optical receiver. The interference can be due to multi-path interference or due to in-band interference. The receivers include a tunable filter for filtering the received optical signal to remove the interference. A frequency offset module processes the received optical signal to determine a frequency offset indicative of the difference between the carrier frequencies of a modulated optical signal and an interference optical signal. The offset frequency and a bandwidth determined by the frequency offset module can be used to adjust the tunable filter to remove the interference signal from the received signal.

Claim (Index 10):
A method comprising:\n generating, using a laser of an optical transmitter, an optical signal having a carrier frequency; modulating, using a modulator of the optical transmitter, the optical signal with a data signal to generate a modulated optical signal; tuning, using a laser tuner of the optical transmitter, the carrier frequency of the optical signal; and receiving, at a processor of the optical transmitter, a frequency offset of an interference signal from a receiver, the frequency offset of the interference signal indicative of a difference between a received optical signal received at the receiver and a noise optical signal; dynamically comparing, using the processor in response to receiving the frequency offset, the frequency offset with a bandwidth of the modulated optical signal; and controlling, by the processor based on the frequency offset being less than the bandwidth of the modulated optical signal, the laser tuner to tune the carrier frequency of the optical signal such that the received frequency offset is greater than the bandwidth of the modulated optical signal.
