MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202611008424 A) filed by Indian Institute Of Technology, New Delhi, on Jan. 28, for 'microcontroller-based servo-lock loop system and method for laser frequency stabilization.'
Inventor(s) include Santra, Bodhaditya; Singh, Deepshikha; Yadav, Hemant; and Jain, Kripali.
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 provides a laser frequency stabilization module (100) comprising a microcontroller (102), a plurality of one analog-to-digital converter (ADC) inputs (104) (a, b) coupled to the microcontroller (102), a plurality of one filter circuits (106) (a, b, c) coupled to the at least one ADC input, a digital-to-analog converter (DAC) module (108) coupled to the microcontroller (102), and a function generator output (110) coupled to the microcontroller (102). The microcontroller (102) is configured to implement a digital control algorithm for laser frequency stabilization based on an error signal received at the plurality of one analog-to-digital converter (ADC) inputs (104) (a, b), process the error signal to generate a correction signal, control the digital-to-analog converter (DAC) module (108) to output the correction signal for adjusting laser frequency, control the function generator output (110) to generate a scanning waveform for initial locking, automatically identify and lock to a spectral peak, continuously monitor and adjust the laser frequency to maintain lock, and transmit spectral data to a host computer via a communication interface (114)."
