MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050408 A) filed by Sriperambudur Archita; and Sriperambudur Karthik, Hyderabad, Telangana, on April 20, for 'system and method for optical communication and data transmission through liquid media using intensity-modulated visible light & spatially integrating photovoltaic receiver.'
Inventor(s) include Sriperambudur Archita; Shanthi Makka; Sriperambudur Joshitha; Sriperambudur Karthik; Jnanadrushti Saahasradh; Sriperambudur Shloka; and Jnanadrushti Ishaanvi.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a liquid-medium optical communication system for transmitting and recovering analog information through water and other liquid environments using intensity-modulated visible light and a photovoltaic or optical receiver. The invention enables recovery of analog information in liquid media by preserving temporal modulation using spatial integration of optical signals at a photovoltaic receiver. Experimental validation demonstrates reliable operation in multiple configurations including both source and receiver submerged, source external to the liquid with receiver submerged, and source submerged with receiver external to the liquid. Transmission is validated in clear, hazy, non-transparent, emulsified, oil-based, layered, turbulent, and dynamically disturbed liquids, including conditions involving scattering, bubbles, misalignment, reflections, and interface propagation. Unlike acoustic, RF, or laser-based digital optical systems, the invention preserves temporal modulation continuity despite liquid-induced attenuation, without requiring coherent sources, digital encoding, synchronization, or complex signal processing. The system is adaptable for underwater sensing, monitoring, signaling, diver communication, and representative submarine interface applications, without limitation to specific depths, voltages, or geometrical arrangements."
