Latest Patents

Chandrasekhar Roychoudhuri holds two notable patents that exemplify his innovative capabilities:

1. **Optical Communication System**: This invention is designed to suppress the generation of crosstalk, even in cases of small wavelength spacing and high bit-rate modulation. The system includes an Nth order harmonic generating device positioned before a demultiplexer, allowing the frequency of the light wave to be upconverted or downconverted by N times. This results in increased frequency spacing between carriers, facilitating easier separation of optical signals and permitting denser wavelength division multiplexing (WDM) channels, as well as higher data rates per channel.

2. **Optical Circuit with Harmonic Generator**: This patent outlines an optical circuit that integrates demultiplexing and optical detection functionalities with minimal crosstalk. Similar to the first patent, it employs an Nth order harmonic generation device positioned before the demultiplexer to convert the frequency or downconvert the wavelength of the demultiplexed light wave. The multiplexed signal can be upconverted at the receiver station, enhancing the spacing between optical channels either simultaneously or one at a time.
