👋 Hello
I’m Abhigyan
PhD student at CeNSE, Indian Institute of Science.
Laser engineer by day.
🎶 Bedroom musician and
Artist by night.
🔬 What I Do
I’m a Prime Minister’s Research Fellow at the Centre for Nano Science and Engineering (CeNSE), IISc, where I focus on the [design] and [development] 
of advanced high-power fiber lasers for cutting-edge applications in biomedical imaging 
and silicon microfabrication 
.
I have developed:
- A broadly tunable pulsed Raman laser, enabling photoacoustic imaging in both the visible and near-infrared window.
- A non-contact, high-accuracy temperature sensing system for semiconductor microfabrication using a spectrally shaped supercontinuum source.
Featured in the “Spotlight on Optics” by the Optica Publishing Group.
📚 Teaching & Outreach
I teach interdisciplinary courses to both undergraduate and master’s students:
Computational Photonics
Biostatistics & Data Analysis
Differential Equations
Light and Biomolecules
🎤 I engage in science outreach through IISc Open Day, deliver interactive lectures in schools, and support education access via the Notebook Drive Initiative.
🎨 Creative Corner
I produce and play my own music.
I sketch hyperrealistic portraits.
I write blogs and short stories.
My research areas
Raman fiber laser
Raman fiber lasers are wavelength-agile power sources that exploit stimulated Raman scattering to generate high-power output at wavelengths inaccessible to rare-earth-doped fiber lasers.
Supercontinuum sources
A supercontinuum source is a broadband light source that emits a wide spectrum of wavelengths, generated through nonlinear processes in optical fibers.
Photoacoustic Imaging
Photoacoustic imaging combines optical excitation with ultrasonic detection to provide high-resolution images of optical absorption, and my work has focused on developing custom laser modules tailored for photoacoustic microscopy applications.
Seminconductor metrology
Precise and fast temperature measurement techniques using supercontinuum sources to monitor and control semiconductor device fabrication.
CNC machines
Optomechanical components fabricated using a 3D-printed CNC machine leverage additive manufacturing and computer-controlled machining for low-cost, customizable, and precise production.
