Multimodal Optical Feature Extraction with a Free-Space Photonic Extreme Learning Machine
Anushka Kumari, Anushree Khisti, Abhinav Choube +3
Photonic extreme learning machines (PELMs) replace a digitally trained hidden layer by a fixed optical transformation, allowing a high dimensional feature map to be generated by ph…
PhoQuPy: A Python framework for Automation of Quantum Optics experiments
Srivatsa Murali, Anshuman Kumar
We present the automation of a confocal photoluminescence (PL) scanning system for the identification and characterization of single-photon emitters (SPEs) in quantum materials. Th…
Inverse Design of the Topology Bandwidth Tradeoff in Valley Photonic Crystals
Devansh Satra, Abhishek Kumar, Anshuman Kumar
Integrated on-chip photonics increasingly relies on wave propagation that remains stable in the presence of fabrication imperfections, tight bends, and dense routing. Valley photon…
Exploring the role of hyperbolicity in surface enhanced Raman sensing
Mihir Kumar Sahoo, Abhay Anand V S, Nihar Ranjan Sahoo +1
A plasmonic nanostructure-based substrate, serving as a surface-enhanced Raman scattering (SERS) substrate, enhances the Raman scattering of molecules. By employing an electron bea…
Electrostatically Controlled Pyrophototronic Effect Enabled Accident Alert System using a Strain-Polarized WS2 Phototransistor
Poulomi Chakrabarty, Sera Sen, Anwesha Chakraborty +5
Event-based dynamic light detection, specifically in low illumination power environments, is a critical requirement in autonomous vehicles. This work reports low optical power phot…
A Surrogate Model for the Forward Design of Multi-layered Metasurface-based Radar Absorbing Structures
Vineetha Joy, Aditya Anand, Nidhi +3
Metasurface-based radar absorbing structures (RAS) are highly preferred for applications like stealth technology, electromagnetic (EM) shielding, etc. due to their capability to ac…
