Title: The Innovations of Robert Corwin

Introduction

Robert Corwin is a notable inventor based in Finksburg, MD (US). He has made significant contributions to the field of optical technology, holding a total of 4 patents. His work primarily focuses on enhancing the performance of optical receivers, which are crucial in telecommunications.

Latest Patents

One of Corwin's latest patents is the "Optical pre-amplifier apparatus and method for receiver performing gain control according to LOS declaration." This invention involves a receiver node that includes an optical amplifier optically coupled to a receiving device, such as a PIN photodiode. The controller inputs received power level values from the receiver to perform gain control. The input signal of an optical receiving device is pre-amplified by an optical amplifier, ensuring that the amplified signal remains within the dynamic range of the receiving device. Upon a loss of signal (LOS) event, the controller sets the gain to a Home Gain value, preventing potential damage to the receiver when the signal is reestablished. Various methods are employed to declare LOS, including comparing received power levels against a threshold.

Another significant patent is the "Gain controlled optically pre-amplified receiver apparatus and method." In this invention, an optical amplifier is added to the input of a photodetector to perform optical pre-amplification of an input optical signal before it is converted to an electrical signal. The controller utilizes a received power level to control the pump power level of a pump injecting light into the optical amplifier. This innovation aims to optimize the optical gain of the amplifier while ensuring efficient operation.
