MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024632 A) filed by Lakshmi Priya Isanaka; and Meenakshi Murugappan, Chennai, Tamil Nadu, on March 2, for 'a supercontinuum-based millimeter wave (mmw) source device.'
Inventor(s) include Lakshmi Priya Isanaka; and Meenakshi Murugappan.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a supercontinuum-based millimeter wave (MMW) 5 source device (100) for generating high-frequency electrical signals. The device comprises an optical pulse generator (110) configured to produce a high-intensity input pump pulse centered at a reference wavelength. This pulse is launched into a Dispersion Decreasing Fiber (DDF) (120) having a core and cladding structure designed to provide a specific chromatic dispersion profile. The chromatic 10 dispersion of the DDF (120) is a convex function of wavelength and decreases linearly along the propagation distance from a positive anomalous dispersion value at the input to a negative normal dispersion value at an effective length. This configuration facilitates adiabatic soliton compression to generate a spectrally flat supercontinuum. A filtering and detection assembly (130), comprising parallel 15 optical filters and a photodetector (140), selects specific spectral components from the flat supercontinuum and converts them into a stable millimeter wave electrical signal through heterodyning."
