  • Vyas, Hardik; Hegde, Ravi S. (Optical Society of America, 2020-07)
    Silicon nitride (Si3N4) subwavelength medium contrast gratings (MCGs) directly integrated with CMOS photodetectors are a promising option for on-chip label-free biosensing. The narrow spectral features required for sensing ...
  • Vyas, Hardik; Hegde, Ravi Sadananda (Society of Photo-Optical Instrumentation Engineers, 2019-04)
    While long-range propagating plasmons have been extensively investigated for implementing on-chip optical sensing platforms, waveguide-excited localized surface plasmon resonance-based sensing systems have not yet received ...
