Title: The Innovations of Ricardo Feced
Introduction
Ricardo Feced is a notable inventor based in Sawbridgeworth, GB. He has made significant contributions to the field of optical technology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is titled "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 several subcarrier reference signals for demodulating frequency channels of the multiplexed signals. The invention compensates for degradations in the generated reference signals by averaging estimates derived from different inputs, enhancing resilience to such degradations. This technology can enable longer system reach and increased optical power margins, ultimately reducing the bit error rate and increasing capacity.
Another significant patent by Feced is the "Method of writing a Bragg diffraction grating." This method involves writing a diffraction grating into a photosensitive optical transmission medium using a first phase mask to generate an interference pattern in a second phase mask substrate. Photolithographic techniques are employed to produce the second phase mask, which is then used to write the diffraction grating. This innovative approach improves line placement in a phase mask by averaging out line placement errors.
