Title: Ranjan Dutta: Innovator in Optical Technologies
Introduction
Ranjan Dutta is a notable inventor based in Lawrenceville, NJ (US), recognized for his contributions to optical technologies. He holds a total of 8 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
Among his latest inventions is the "DWDM channel detection system." This system includes an interferometer coupled to a spectrum analyzer, designed to differentiate additive spontaneous emission (ASE) noise from optical channels in a dense wave-division multiplex (DWDM) signal. The system assumes that channels, if present, are centered at frequencies corresponding to a standardized channel grid. The relative delay of the interferometer is carefully chosen to be greater than the coherence time of the ASE noise but less than that of the channels. The phase delay of the interferometer is adjusted to maximize interference at each grid-aligned frequency, allowing for effective channel detection in the DWDM signal.
Another significant patent is the "Apparatus and method for managing dispersion within an optical add/drop module." This invention comprises a method and apparatus for implementing a relatively low-cost add/drop multiplexer (OADM). It employs pre-demux and post-mux dispersion compensation in a manner that avoids imparting additional dispersion to pass-through wavelength channels in a WDM system.
