MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641017680 A) filed by Srm University, Guntur, Andhra Pradesh, on Feb. 17, for 'a system for performing all optical logic operations in a visible wavelength spectrum.'
Inventor(s) include Katuri Rajakumari; Tupakula Sreenivasulu; Chekuri Venu Gopala Chowdary; Doppalapudi Sravya; Shaik Imamvali; and Valeti Naga Jyothi.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure relates to a system (100) for performing all-optical logic operations in a visible wavelength spectrum. The system (100) comprises a dielectric substrate (110) having a two-dimensional photonic crystal lattice etched into a planar surface (120) to produce a photonic bandgap (140) within the visible range. Linear waveguides (150) defined by line defects guide optical signals toward a resonant cavity formed at an intersection region. A plurality of scattering control elements, comprising sub-wavelength air holes adjacent to the cavity, are configured to reduce out-of-plane scattering losses and enhance in-plane interference. An optical signal processing arrangement (160) includes input (170) and reference ports (190) for receiving optical signals, wherein the reference signal has a controllable phase offset. These signals interact within the resonant cavity via phase-controlled interference to produce a logic output at an output port (220) corresponding to a predefined logic function."
