MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123539 A) filed by Indian Institute Of Technology, Hyderabad, Telangana, on Dec. 8, 2025, for 'a method and a system for gain-equalized broadband amplification using few mode fibers.'
Inventor(s) include Nithyanandan Kanagaraj; and Amala Jose.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure discloses a method and a system for generating a gain-equalised amplified broadband signal using few mode fibers (FMFs). The method comprises amplifying, by a first amplification (FA) unit (102), an input signal to generate a first amplified signal. The input signal is a multi-mode broadband optical signal. Further, the method comprises receiving, by a spatial-spectral filtering (SSF) unit (104), the first amplified signal. Further, the method comprises determining, by the SSF unit (104), a transmission coefficient matrix associated with a target gain value. The method further comprises selectively attenuating power intensity of the first amplified signal. The method further comprises amplifying, by a second amplification (SA) unit (106), the second signal, based on a gain guiding mechanism to generate a second amplified signal as a gain-equalized output signal if the second amplified signal corresponds to the target gain value."
