Physical Review A

Nonlocality of coupling and the retrieval of field correlations with arrays of waveguides

Stefano Minardi

Abstract

Arrays of evanescently coupled waveguides can be used to retrieve simultaneously the first-order correlation functions in multiple-field interferometry. Here it is shown that this remarkable property of waveguide arrays is enabled only by the existence of nonlocal interaction, i.e., non-nearest-neighbor coupling between the waveguides.

Effect of second-order coupling on photon-pair statistics in waveguide structures

Yehonatan Gilead, Yaron R. Silberberg

We investigate a quasi-one-dimensional periodic array of coupled waveguides, with one extended and one bound dimension, incorporating both first- and second-order coupling. We study the evolution of optical fields in this system, and measure quantum correlations when path-entangled photon pairs are launched into them. We observe a surprisingly large and nontrivial effect of second-order coupling on these correlations---while quantum correlations are symmetric when only first-order coupling is present, the introduction of next-nearest-neighbor coupling often breaks the symmetry to reflections.

One-dimensional waveguide coupled to multiple qubits: photon-photon correlations

Yao-Lung L Fang, Huaixiu Zheng, Harold U. Baranger

For a one-dimensional (1D) waveguide coupled to two or three qubits, we show that the photon-photon correlations have a wide variety of behavior, with structure that depends sensitively on the frequency and on the qubit-qubit separation L. We study the correlations by calculating the second-order correlation function in which the interference among the photons multiply scattered from the qubits causes rich structure. In one case, for example, transmitted and reflected photons are both bunched initially, but then become strongly anti-bunched for a long time interval. We first calculate the correlation function including non-Markovian effects and then show that a much simpler Markovian treatment, which can be solved analytically, is accurate for small qubit separation. As a result, the non-classical properties of microwaves in a 1D waveguide coupled to many superconducting qubits with experimentally accessible separation L could be readily explored with our approach.

Photon correlations in two-dimensional waveguide arrays and their classical estimate

Robert Keil, Alexander Szameit, Felix Dreisow +3 more

Interference effects of photon pairs propagating through two-dimensional lattices of evanescently coupled waveguides are theoretically analyzed for input states of independent and path-entangled photons. Their correlation unveils characteristic Hong-Ou-Mandel interferences as well as more complex phenomena unique to these structures. Furthermore, purely classical states of light are used to simulate these quantum interferences in intensity correlation experiments. The results suggest that waveguide arrays can be employed as convenient devices for manipulating quantum states of light.

Single Photon Quantum Walk in Waveguide Arrays with Next-nearest Neighbor Interaction

Surajit Paul, Krishnan Thyagarajan

We show how the next nearest neighbor interaction modifies the photon propagation characteristics in 1-D waveguide arrays and how this enables us to realize a 5 partite W state in an array of 5 equally spaced waveguides.

Classical characterization of biphoton correlation in waveguide lattices

Robert Keil, Felix Dreisow, Matthias Heinrich +3 more

We propose a classical experimental scheme for simulating quantum correlations of path-entangled biphotons, propagating in arbitrary one- or two-dimensional arrays of evanescently coupled waveguides. Our approach requires only intensity and phase measurements and can be used to characterize the evolution of the biphoton wave packet. The precision of the method and its robustness to phase fluctuations are investigated by a statistical analysis.
