Direct generation of two-pair frequency entanglement via dual periodic poling in lithium niobate waveguides
Aakash Warke, Krishna Thyagarajan
In this paper, we address the generation of a two-pair frequency entangled state using type-0 spontaneous parametric down-conversion process in a dual periodically poled lithium ni…
Geneartion of higher dimensional modal entanglement using a three waveguide directional coupler
Divya Bharadwaj, K. Thyagarajan, Michal Karpinski +1
In this paper, we propose a method for the generation of higher dimensional modal entanglement through type II spontaneous parametric down conversion process using a three waveguid…
Generation of modal and path-entangled photons using a domain-engineered integrated optical waveguide device
Jasleen Lugani, Sankalpa Ghosh, K. Thyagarajan
Integrated optical devices are expected to play a promising role in the field of quantum information science and technology. In this paper, we propose a scheme for the generation o…
Increased pump acceptance bandwidth in spontaneous parametric downconversion process using Bragg reflection waveguides
K. Thyagarajan, R. Das, O. Alibart +3
In this paper we show that by suitably tailoring the dispersion characteristics of a Bragg reflection waveguide (BRW) mode, it is possible to achieve efficient photon pair generati…
