Journal ArticleDOI
Narrow band filter using 1D periodic structure with defects for DWDM systems
TL;DR: In this article, a 1D binary periodic structure with defect was analyzed using Transfer Matrix Method (TM) and FDTD simulation, and it was shown that the field is localised within the defect for the passband frequency.
Journal ArticleDOI
High resolution wide range pressure sensor using hexagonal ring and micromachined cantilever tips on 2D silicon photonic crystal
TL;DR: In this paper, a two-dimensional triangular/hexagonal lattice silicon photonic crystal (Si) arrangement with hexagonal unit cells and two micromachined silicon cantilever tips is proposed for optical sensing of pressure.
Proceedings ArticleDOI
An efficient wavelet analysis for ECG signal processing
Anandarup Mukherjee,K. K. Ghosh +1 more
TL;DR: A comparative study on the choice of some of the conventionally used wavelets and their corresponding accuracies for ECG feature extraction by R peak detection and the B Spline wavelet transform of ECG signal is found to be the most efficient means ofECG signal processing.
Journal ArticleDOI
Further enhancement of light extraction efficiency from light emitting diode using triangular surface grating and thin interface layer
TL;DR: From the analysis, it is found that the patterned film is suitable for near-infrared LED and the optimized structure, which gives maximum improvement at around 1.040 μm wavelength, is determined and fabricated using soft lithography.
Journal ArticleDOI
Efficient splitting of broadband LED light into narrowbands using superlensing effect and defects on its top 2D photonic crystal
TL;DR: In this paper, a photonic crystal (PhC) based structure is proposed for efficient splitting of light from broadband Light Emitting Diode (LED) into multiple narrowband sources.
