Latest Patents

One of Savory's latest patents is for a coherent receiver. This device receives a set of signals that are spaced in phase or phase and polarization, along with a reference signal. The coherent receiver processes these signals to identify which one has the closest association with the reference signal, selecting it as the optimum output. This technology effectively de-rotates the phase slip between the input and reference signals in discrete steps, allowing for repeated selection of the best output. The processing can be performed in either the analogue or digital domains, utilizing techniques such as amplitude comparison and cross-correlation. This innovation aims to simplify the components needed for high-frequency optical communication, making them more reliable and cost-effective.

Another significant patent by Savory is a digital compensation system for optical transmission. This receiver features a polarization diverse and phase diverse coherent optical receiver, along with a digital adaptive equalizer. This system compensates for distortions in the optical signal caused by the transmission path. By mapping the entire field of the optical signal, including phase and polarization information, it allows for comprehensive compensation of impairments like chromatic dispersion and polarization mode dispersion (PMD). This technology can upgrade existing transmission routes, increasing capacity without the need for costly fiber replacements.
