Arbitrary vector beam generation in semiconductor quantum dots
Samit Kumar Hazra, P. K. Pathak, Tarak Nath Dey
We have proposed an arbitrary vector beam (VB) generation scheme in a thin disk-shaped quantum dot (QD) medium considering phonon interaction. The QD biexciton system exhibits inte…

Nondegenerate two-photon lasing in a single quantum dot
Samit Kumar Hazra, Lava Kumar Addepalli, P. K. Pathak +1
We propose two-mode two-photon microlaser using a single semiconductor quantum dot grown inside a two-mode microcavity. We explore both incoherent and coherent pumping at low tempe…

Structured beam controlled super-resolution in quantum dots via rapid adiabatic passage
Partha Das, Samit Kumar Hazra, Tarak Nath Dey
We theoretically investigate rapid adiabatic passage (RAP) based super-resolution microscopy in a two-level quantum dot (QD) system. The system consists of a QD interacting with tw…
