van der Waals Nanogap Loading of a \ce{TiO2} Nanobar Metasurface for Dual-Channel Fano Refractive Index Sensing
Shoumik Debnath, Sudipta Saha
Filling the gap of a \ce{TiO2} nanobar-pair metasurface with -\ce{MoO3}, a biaxial orthorhombic crystal, produces two high- Fano resonances with unequal quality factors: $Q_\…
Polarization-Selective Near-Perfect Absorption via Mie-Type Resonance in van der Waals Anisotropic ReS/-MoO/Au Heterostructure
Shoumik Debnath, Sudipta Saha
We investigate polarization-selective absorption in a visible-wavelength heterostructure consisting of a ReS stripe grating, an -MoO spacer, and an Au back-reflector usi…
Polarization-Multiplexed Spatial Filtering in a Symmetric \ce{TiO2} Metasurface with an Anisotropic van der Waals Gap Fill
Shoumik Debnath, Sudipta Saha
Finite-difference time-domain simulations of a symmetric \ce{TiO2} nanobar-pair metasurface with a 60~nm -\ce{MoO3} gap fill give two Fano resonances that are selected by the in…
Inverse Design Validated Optimization of Lead-Free CsCuCl Visible-Light Microring Resonators Using a Coupled DFT-FDTD Framework
Shoumik Debnath, Sudipta Saha
Microring resonators are indispensable for wavelength filtering, sensing, and on-chip signal routing in photonic integrated circuits, yet visible-wavelength implementations using e…
Spectral singularity enhances transverse spin
Mounica Mahankali, Sudipta Saha, Nirmalya Ghosh +1
We study the transverse spin and the Belinfante spin momentum in a gain-loss balanced waveguide, known to be one of the first and most studied examples of -symmetric…
