Due to the recent interest in nanoparticles for both new functionalities and health-and-environment risks-related particle emissions of vehicles and industries, integrated-photonic single-particle …
We present a theoretical investigation, based on the tight-binding Hamiltonian, of efficient second harmonic generation (SHG) in the lattice-matched N-doped (GaP)N/(Si2)M short-period superlattice …
We present a theoretical investigation of efficient second harmonic generation in the cubic lattice-matched N-doped Si/GsP multiple quantum well system integrated in a strip waveguide in the silico…
Non-Hermitian photonics has attracted increasing attention especially for sensing applications. Two coupled optical systems, designed to work at the “exceptional point”, exhibit a strong spectr…
Quartz enhanced photo acoustic spectroscopy (QEPAS) has gained a growing interest in recent years for gas sensing technology because of the high sensitivity provided by sharp resonant tuning forks …
