I am a graduate student in CeNSE, IISc Bengaluru. My research area is development of Silicon Nitride platform for Quantum Photonics. In free time I play guitar, soccer and listens to music. My bachelor's was in Physics and Mathematics from Panjab University and master’s in Optoelectronics and Optical communication from Indian Institute of Technology Delhi
Photonics is a vital part of our daily life, from LEDs to the cutting of metals and now Quantum technology.
Quantum technology for communication and computing is witnessing exponential growth in research and commercial applications. Quantum technology relies on the generation, manipulation, and detection of a single photon. On-chip integrated photonics is one of the ways to achieve this and is better in terms of scalability and does not require cryogenic temperature and high vacuum, unlike Superconducting circuits and Ions/Atom trapping. For the generation of single-photon, one can exploit on-chip nonlinear processes such as spontaneous four-wave mixing (SFWM) and spontaneous down-conversion (SPDC). Furthermore, unlike silicon, silicon nitride has no two-photon absorption, has a higher figure-of-merit, and has a broad transparency range from 400 nm to 8 μm which opens the window for bio-sensing applications. In this work, on-chip generation and detection of single-photon is the primary objective.
