Kerr-enhanced amplification of three-wave mixing and emergent masing regimes
Ragheed Alhyder, Rishabh Sahu, Johannes M. Fink +2
Integrated optical microresonators exploiting either second-order () or third-order () nonlinearities have become key platforms for frequency conversion, low-nois…
Generation of Gaussian Schell-model fields as mixtures of their coherent modes
Abhinandan Bhattacharjee, Rishabh Sahu, Anand K. Jha
Gaussian Schell-model fields are examples of spatially partially coherent fields, which in recent years have found several unique applications. The existing techniques for generati…
Angular Lens
Rishabh Sahu, Swati Chaudhary, Kedar Khare +3
We propose a single phase-only optical element that transforms different orbital angular momentum (OAM) modes into localized spots at separated angular positions on a transverse pl…
Single-shot measurement of the orbital-angular-momentum spectrum of light
Girish Kulkarni, Rishabh Sahu, Omar S. Magana-Loaiza +2
The existing methods for measuring the orbital-angular-momentum (OAM) spectrum suffer from issues such as poor efficiency, strict interferometric stability requirements, and too mu…
