Latest Patents
Clesca's latest patents showcase innovative methods in optical transmission technology. His first patent involves a transmission method and an optical link that utilizes multiplexing. This invention features a spectrum multiplexing link where an amplifying fiber amplifies multiple multiplexed carrier waves. Notably, this invention ensures a flat spectrum distribution of the gain in the amplifying fiber, adapting to varying numbers of carrier waves. It employs servo-controlled power to regulate light amplified by the fiber, which is independent of the carrier waves. The configuration includes using light characterized by reverse amplified spontaneous emission, filtered and detected by a photodiode to control the power supplied to laser diodes for fiber pumping. This invention holds particular significance for implementing optical transmission networks.
The second patent Clesca holds is a regulated optical amplifier that also employs an amplifying optical fiber to enhance multiple wavelength-multiplexed carrier waves. This innovation enables the gain perceived by each carrier wave to be maintained, even with variations in total input power. Similar to his first patent, Clesca applies the principles of servo-controlled power using amplified spontaneous 'reverse' emission light, which again is filtered and detected by a photodiode to regulate the power supplied to laser diodes for pumping the fiber. This solution is crucial for advancing optical transmission networks.
