Six-wave mixing of optical and microwave fields using Rydberg excitations in thermal atomic vapor
Tanim Firdoshi, Sujit Garain, Suman Mondal +1
Rydberg EIT-based microwave sensing has limited microwave-to-optical conversion bandwidth due to fundamental limitation in the optical pumping rate to its dark state. We demonstrat…
Study of geometric phase using classical coupled oscillators
Sharba Bhattacharjee, Biprateep Dey, Ashok K Mohapatra
We illustrate the geometric phase associated with the cyclic dynamics of a classical system of coupled oscillators. We use an analogy between a classical coupled oscillator and a t…
Nonlinear magnetoelectric effect in atomic vapor
Sushree S. Sahoo, Soumya R. Mishra, G. Rajalakshmi +1
Magnetoelectric (ME) effect refers to the coupling between electric and magnetic fields in a medium resulting in electric polarization induced by magnetic fields and magnetization…
Mirrorless optical parametric oscillator inside an all-optical waveguide
Sushree S Sahoo, Snigdha S Pati, Ashok K mohapatra
Mirrorless optical parametric oscillator (MOPO) is a consequence of intrinsic feedback provided by the nonlinearity in a medium due to the interaction of a pair of strong counter-p…
Study of Rydberg blockade in thermal vapor
Arup Bhowmick, Dushmanta Kara, Ashok K. Mohapatra
We present the experimental demonstration of Rydberg blockade in thermal atomic vapor where the atoms are not necessarily be frozen. We show that not all the interacting atoms but…
Rydberg interaction induced enhanced excitation in thermal atomic vapor
Dushmanta Kara, Arup Bhowmick, Ashok K. Mohapatra
We present the experimental demonstration of interaction induced enhancement in Rydberg excitation or Rydberg anti-blockade in thermal atomic vapor. We have used optical heterodyne…
