With a remarkable portfolio of two patents, she has demonstrated her expertise and innovative spirit, particularly in developing cutting-edge technologies that enhance the functionality and efficiency of electronic and optical systems.

Latest Patents

One of Andrea's latest patents is the "Opto-electronic frequency divider circuit and method of operating same." This invention features a circuit that includes an electro-optical mixer, such as an electro-optical Mach-Zehnder modulator, which shows non-linear behavior. The modulator receives inputs from an optical signal at the frequency to be divided, along with an electric signal corresponding to that division's frequency. The resulting optical output exhibits a modulation spectrum that contains the frequency difference between the input frequencies. After conversion into an electric signal, the output undergoes a filtering action to extract the frequency difference component, which is utilized for mixing and as the output signal from the divider. The predominant application for this technology is within Optical Time Division Multiplexing (OTDM) systems, where it helps to extract a synchronism signal at the tributary signal frequency.
