A bimetallic nanorod dimer biosensor based on localized surface plasmon resonance (LSPR) has been proposed in this thesis. Larger absorption and stronger electric eld coupling have been achieved when a gold (Au) core ...

Semiconductor photodetectors working in the mid-infrared range of operation are important because of their extensive applications in chemical sensing, gas monitoring, medical diagnostics, infrared imaging, molecular ...

In this work, we propose room-temperature plasmonic crystal based nanolaser with low divergence emission. Usually, performance of nanolasers based on plasmonic crystal nanocavity is a ected by a couple of issues: coupling ...

Quantum cascade laser (QCL) is a promising candidate for comparatively less developed terahertz spectral range. Design-dependent emission frequency and sequential pumping make QCL suitable for Hetero-active region ...

Silicon solar cell photovoltaics offer the possibility of harvesting almost limitless electromagnetic energy radiated from the sun. However, wide-spread adoption of these solar cells requires that greater conversion ...
