Hitaishi V

Hitaishi V is a physicist working on nonlinear optics and integrated photonics, with a focus on supercontinuum generation in dispersion-engineered waveguides. He completed his PhD in Physics at VIT-AP University in 2025, working with Prof. Nandam Ashok on the design and numerical analysis of chalcogenide waveguides. His published work spans mid-IR supercontinuum generation in D-shaped and semi-ellipse core waveguides at 4 μm, broadband supercontinuum in dispersion-engineered As2Se3–GeAsSe–GeAsS waveguides at 6 μm, and tellurium-based chalcogenide waveguides for dispersion and supercontinuum applications. Alongside this he has contributed to Tamm–Fano plasmonic and slot-waveguide microring sensors for refractive-index and glucose sensing. He writes open-source computational photonics. His package photonics_helper is published on PyPI and carries a generalised nonlinear Schrödinger equation solver with vector and multimode engines, a Raman response database spanning 44 materials, second- and third-order nonlinear optics, FROG trace retrieval and a transfer-matrix method for distributed Bragg reflectors. In the lab he works on the computational side of photonic materials: inverse design and physics-informed machine learning applied to micro-resonators and gain media. Before his PhD he studied at JSS College of Arts, Commerce and Science, Mysuru, and at Dayananda Sagar College, Bengaluru. He is GATE-qualified in Physics.
