Title: Vighen Pacradouni: Innovator in Electro-Photonic Technology
Introduction
Vighen Pacradouni is a notable inventor based in Montreal, Canada. He has made significant contributions to the field of electro-photonic technology, holding 2 patents that showcase his innovative approach to optical communication systems.
Latest Patents
His latest patents include an "Electro-photonic circuit comprising burst-mode optical receiver." This invention features a burst-mode optical receiver designed for an optical line terminal (OLT) of a passive optical network (PON). The circuit includes a variable optical attenuator (VOA), a photodiode (PD), a transimpedance amplifier (TIA), and a feedback/control circuit. This design allows for the adjustment of the bias voltage of the VOA in response to the burst-mode optical input signal level, providing an attenuated optical output signal to the PD with a narrower dynamic range. This innovation mitigates the need for a burst-mode TIA with a large dynamic range and enables fast switching.
Another significant patent is for "Electro-photonic transmitter and receiver integrated circuits (chiplets) for co-packaged optics and methods of operation." This invention discloses electro-photonic integrated circuits that comprise optical transmitters and receivers. The design features a monolithically integrated electro-absorption modulated laser (EML) that operates bidirectionally. The vertically stacked waveguides for the laser and electro-absorption modulator (EAM) are optically coupled using a laterally tapered vertical optical coupler. The EML includes integrated electronic circuitry for driving the laser and EAM, enhancing the efficiency of optical communication.
