Our numerical investigations demonstrate that this antenna in a 64 × 64 phased array configuration is capable of producing desired far-field radiation patterns.

In this platform, we aim to efficiently manipulate and detect quantum states by combining superconducting single photon detectors and modulators.

To properly use these components in the implementation of different quantum protocols, photons with different properties are required. In this paper, we theoretically demonstrate a flexible source of correlated photons built on the LNOI waveguide of a special geometry. This source is based on the parametric down-conversion (PDC) process, in which the signal and idler photons are generated at the telecom wavelength and have different spatial profiles and polarizations, but the same group velocities. Distinguishability in polarizations and spatial profiles facilitates the routing and manipulating individual photons, while the equality of their group velocities leads to the absence of temporal walk-off between photons. We show how the spectral properties of the generated photons and the number of their frequency modes can be controlled depending on the pump characteristics and the waveguide length. Finally, we discuss special regimes, in which narrowband light with strong frequency correlations and polarization-entangled Bell states are generated at the telecom wavelength. author: - first_name: Lena full_name: Ebers, Lena id: '40428' last_name: Ebers - first_name: Alessandro full_name: Ferreri, Alessandro id: '65609' last_name: Ferreri - first_name: Manfred full_name: Hammer, Manfred id: '48077' last_name: Hammer orcid: 0000-0002-6331-9348 - first_name: Maximilian full_name: Albert, Maximilian last_name: Albert - first_name: Cedrik full_name: Meier, Cedrik id: '20798' last_name: Meier orcid: https://orcid.org/0000-0002-3787-3572 - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 - first_name: Polina R. full_name: Sharapova, Polina R. id: '60286' last_name: Sharapova citation: ama: 'Ebers L, Ferreri A, Hammer M, et al.

We show proof-of-principle detection of evanescently coupled photons of 1550 nm wavelength using bidirectional waveguide coupling for two orthogonal polarization directions. We investigate the internal detection efficiency as well as detector absorption using coupling-independent characterization measurements. Furthermore, we describe strategies to improve the yield and efficiency of these devices. article_type: original author: - first_name: Jan Philipp full_name: Höpker, Jan Philipp id: '33913' last_name: Höpker - first_name: Varun B full_name: Verma, Varun B last_name: Verma - first_name: Maximilian full_name: Protte, Maximilian id: '46170' last_name: Protte - first_name: Raimund full_name: Ricken, Raimund last_name: Ricken - first_name: Viktor full_name: Quiring, Viktor last_name: Quiring - first_name: Christof full_name: Eigner, Christof id: '13244' last_name: Eigner orcid: https://orcid.org/0000-0002-5693-3083 - first_name: Lena full_name: Ebers, Lena id: '40428' last_name: Ebers - first_name: Manfred full_name: Hammer, Manfred id: '48077' last_name: Hammer orcid: 0000-0002-6331-9348 - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Richard P full_name: Mirin, Richard P last_name: Mirin - first_name: Sae full_name: Woo Nam, Sae last_name: Woo Nam - first_name: Tim full_name: Bartley, Tim id: '49683' last_name: Bartley citation: ama: 'Höpker JP, Verma VB, Protte M, et al.
