Title: Innovations of Olga Nedzhvetskaya

Introduction

Olga Nedzhvetskaya is a prominent inventor based in Eatontown, NJ (US), known for her significant contributions to optical processing technology. With a total of nine patents to her name, she has made remarkable advancements in the field of optical signal processing.

Latest Patents

One of her latest patents is a format insensitive and bit rate independent optical preprocessor. This invention presents a method and circuit for an all-optical format independent preprocessor that processes arbitrary optical input signals. It converts a Non-Return-to-Zero (NRZ) signal to a Pulse-Return-to-Zero (PRZ) signal, or amplifies Return-to-Zero (RZ) signals. The method involves subtracting a delayed copy of the signal from the original, effectively doubling its frequency and inserting a pulse at each transition of the original signal. In a preferred embodiment, this stage is implemented via an integrated Semiconductor Optical Amplifier (SOA) in each arm of an asymmetric interferometric device. The asymmetry consists of a delay element in one arm. The entire device is fabricated on a semiconductor substrate, allowing for compactness and minimizing interconnectivity losses and overall power consumption. The output of the preprocessor, which has a significant frequency component at its original clock rate, can then be fed to a clock recovery stage for all-optical clock recovery.
