Latest Patents

Richard holds a patent for "Reference phase and amplitude estimation for coherent optical receiver." This invention focuses on an optical receiver that demodulates optical orthogonal frequency division multiplexed signals. It generates multiple subcarrier reference signals, each designed for demodulating a frequency channel of the multiplexed signals. The technology compensates for degradations in the generated reference signals by averaging estimates derived from different inputs, enhancing resilience to various degradations. This method can include time averaging to address amplification noise and frequency averaging to counteract phase drift caused by reduced source coherence. The advancements can lead to longer system reach and increased optical power margins, ultimately reducing the bit error rate and increasing capacity through higher bit rates or additional frequency channels.
