MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202611002040 A) filed by Chandigarh University, Mohali, Punjab, on Jan. 8, for 'multi-functional optical antenna system for parallel fso-vlc communication and nano-biosignal monitoring.'
Inventor(s) include Dr. Ritu Gupta; and Dr. Sandeep Kaur.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a multi-functional optical antenna system for parallel FSO-VLC communication and nano-biosignal monitoring technologies with advanced nano-biosensing capabilities, specifically designed for EMI-neutral environments. The system architecture integrates wavelength-optimized transmitters such as 1550 nm laser diodes, adaptive modulation schemes (NRZ/QAM), and bowtie nanoantenna arrays that enhance fluorescence and Raman signals by nearly threefold. To overcome atmospheric attenuation in foggy corridors, a multi-hop decode-and-forward relay framework ensures resilient long-range communication. On the receiving side, a PIN photodiode provides dual functionality, enabling both high-speed data decoding and real-time biosignal acquisition. An intelligent diagnostics dashboard further supports adaptive feedback control by visualizing key metrics including Bit Error Rate (BER), Signal-to-Noise Ratio (SNR), and excitation intensity profiles."
