Latest Patents
One of his latest patents is titled "Apparatus and method for reducing SPM/GVD in optical systems." This invention discloses an optical transmission system designed to minimize non-linear distortion caused by the interaction of Self-Phase Modulation (SPM) and Group Velocity Dispersion (GVD). The system includes a transmitter that provides signals at a first optical wavelength, a transponder for converting this wavelength to a second optical wavelength, and various components such as optical transmission fiber spans and amplifiers. The transponder also features a device that smooths the edges of optical pulses, transforming sharp-edged pulses into a Gaussian shape, which improves the overall performance of the system.
Another significant patent by Ottolenghi is "Suppression of polarization hole burning with an acousto-optic modulator." This invention addresses the issue of polarization hole burning in rare-earth-doped fiber amplifiers within optical communication systems. The apparatus includes a polarization-fixing device and an acousto-optic modulator that orthogonally converts the polarization of the optical carrier, enhancing the efficiency of the communication system.
