Generation of Entangled Photon Pairs from a Silicon Bichromatic Photonic Crystal Cavity
<p>Integrated quantum photonics leverages the on-chip generation of nonclassical states of light to realize key function-<br>alities of quantum devices. Typically, the generation of such nonclassical states relies on whispering gallery mode<br>resonators, such as integrated optical micro-rings, which enhance the efficiency of the underlying spontaneous non-<br>linear processes. While this kind of resonators excel in maximizing either the temporal confinement or the spatial<br>overlap between different resonant modes, they are usually associated with large mode volumes, imposing an intrin-<br>sic limitation on the device efficiency and footprint. Here, we engineer a source of time-energy entangled photon<br>pairs based on a silicon photonic crystal cavity, implemented in a fully CMOS-compatible platform. In this device,<br>resonantly enhanced spontaneous four-wave mixing converts pump photon pairs into signal/idler photon pairs at the<br>energy-conserving condition in the telecommunication C-band. The design of the resonator is based on an effective<br>bichromatic confinement potential, allowing to achieve up to 9 close-to-equally spaced modes in frequency, while pre-<br>serving small mode volumes, and the whole chip, including grating couplers and access waveguides, is fabricated in<br>a single run on a silicon-on-insulator platform. Besides demonstrating efficient photon pair generation, we also im-<br>plement a Franson-type interference experiment, demonstrating entanglement between signal and idler photons with<br>a Bell inequality violation exceeding 5 standard deviations. The high generation efficiency combined with the small<br>device footprint in a CMOS-compatible integrated structure opens a pathway towards the implementation of compact<br>quantum light sources in all-silicon photonic platforms.</p>

Stability and electronic properties of K-Sb and Na-Sb binary crystals from high-throughput ab initio calculations
<p>This is the dataset to the identically named publication. All data is stored in an AiiDA archive.</p> <p>In a high-throughput analysis based on density-functional theory (DFT) with the advanced r2SCAN functional, we focus on the two families of binary crystals with K-Sb and Na-Sb compositions that are expected to form during evaporation growth of multi-alkali antimonide photocathodes. Starting from an initial pool of structures mined from existing computational databases, we employed automatized routines included in the in-house developed library aim2dat to determine the stability and the electronic properties of the aforementioned systems. We analyze the formation energy, the band structure and the projected density of states of selected stable compounds.</p>
