Integrated photonics for quantum repeaters
Tiff Brydges
University of Geneva, Switzerland
A key component of quantum communication is the distribution of entanglement through networks, however this comes with several challenges. One of the most significant is that direct transmission of quantum information between two nodes via a standard fibre link is unfeasible for transmission distances of more than a few hundred kilometres [1]. A solution is the ‘quantum repeater’ architecture, which distributes entanglement between two nodes via an intermediate repeater node [2]...

Second harmonic generation in modal phase-matched AlGaAs-on-insulator waveguides

Technical University of Denmark, Denmark
We designed a second harmonic generation (SHG) device utilizing the fundamental TE-TM modes to achieve phase matching, and experimentally investigated the relationship between the phase matching wavelength and the waveguide width on the AlGaAs-on-insulator platform. A SHG efficiency of 201% W-1 cm-2 is obtained with a broad bandwidth of 7.6nm in the 1-mm-long waveguide.

We demonstrate experimentally critical coupling for nonlinear conversion in grating-coupled Fabry-Pérot planar microcavities known as Cavity-Resonant Integrated Grating Filters (CRIGFs).
Novel asymmetric designs offer Q-factors from 1000 to 7000 and allow critical coupling with maximised SHG.
We developed an improved coupled-mode model for the linear and non-linear spectral response of CRIGFs which allows accurate insight on the intrinsic and coupling losses in these microcavities.

Broadband second harmonic generation by birefringent phase matching in an X-cut LiNbO3 membrane

femto-st, France
We designed an X-cut lithium niobate (LiNbO3) membrane dedicated to type I second harmonic generation (SHG) at telecom wavelength. A competitive conversion efficiency compared to a quasi-phase-matched configuration with the advantage of a broadband response of 100nm is shown.

Hybrid photonic devices represent a promising solution to the effective on-chip integration of all the components required for the generation, manipulation and detection of non-classical states of light encoding quantum information. We present an AlGaAs source of highly entangled photon pairs envisioned for the hybridization with silicon-on-insulator integrated platforms, in order to take benefit from the strong second order nonlinearity and the compliance with electrical pumping of the III-V platform and the maturity and CMOS compatibility of silicon photonic circuitry, enabling a wide variety of quantum information applications.
