Latest Patents

One of Erji Mao's latest patents is titled "In-band optical interference mitigation for direct-detection optical communication systems." This patent discloses systems, methods, and apparatus designed to mitigate the effects of interference signals on optical signals received at direct-detection optical receivers. The optical receivers are capable of attenuating interference noise signals that arise from the interference between a transmitted optical signal and additional signals received at the optical receiver. The interference can result from multi-path interference or in-band interference. The receivers incorporate a tunable filter that filters the received optical signal to eliminate 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 utilized to adjust the tunable filter, effectively removing the interference signal from the received signal.
