Dielectric metasurface-assisted cavity ring-down spectroscopy for thin-film circular dichroism analysis
Ankit Kumar Singh, Zhan-Hong Lin, Min Jiang +2
Chiral molecules show differences in their chemical and optical properties due to different spatial arrangements of the atoms in the two enantiomers. A common way to optically diff…
Influence of the coherence of spectral domain interference of Fano resonance on the degree of polarization of light
Shyamal Guchhait, Devarshi Chakrabarty, Avijit Dhara +3
We show an intriguing connection between the coherence of spectral domain interference of two electromagnetic modes in Fano resonance and the resulting degree of polarization of li…
Broadband Four-Wave Mixing Enhanced by Plasmonic Surface Lattice Resonance and Localized Surface Plasmon Resonance in an Azimuthally Chirped Grating
Abhik Chakraborty, Parijat Barman, Ankit Kumar Singh +8
Plasmonic enhancement of nonlinear light-matter interaction can be achieved via dedicated optimization of resonant plasmonic modes that are spectrally matched to the different wave…
Nonlinear optical signal generation mediated by a plasmonic azimuthally chirped grating
Parijat Barman, Abhik Chakraborty, Denis Akimov +7
The deployment of plasmonic nanostructures to enhance nonlinear signal generation requires effective far-to-near field coupling and phase matching for frequency conversion. While t…
Spectrometer-free optical hydrogen sensing based on Fano-like spatial distribution of transmission in a metal-insulator-metal plasmonic Doppler grating
Yi-Ju Chen, Fan-Cheng Lin, Ankit Kumar Singh +2
Optical nanosensors are promising for hydrogen sensing because they are small, free from spark generation, and feasible for remote optical readout. Conventional optical nanosensors…
Signal and Noise Analysis for Chiral Structured Illumination Microscopy
Shiang-Yu Huang, Ankit Kumar Singh, Jer-Shing Huang
Recently, chiral structured illumination microscopy has been proposed to image fluorescent chiral domains at sub-wavelength resolution. Chiral structured illumination microscopy is…
