Topical Collection Information

Dear Colleagues,

The Single Photon Workshop 2019 is the ninth installment in a series of workshops on single-photon technologies and applications. SPW 2019 is intended to bring together a broad range of people with interests in single-photon sources, single-photon detectors, photon entanglement, and their use in scientific and industrial applications. It will be an exciting opportunity for those interested in these technologies to learn about the state-of-the-art and to foster continuing partnerships with others seeking to advance the capabilities of such technologies.

Associated with this conference will be this Special Issue. The Special Issue is not limited to the works presented during the conference but is open to all contributions related to the world of single photons.

Papers are solicited in the following areas:

  • Single-photon detectors: devices, circuits, and systems to achieve single-photon sensitivity;
  • Single-photon sources: materials, schemes, and architectures to generate and control light emission at single photon level;
  • Applications: single-photon technologies for scientific and industrial applications, from ground to space and from life science to quantum information processing;
  • Metrology/validation techniques and instrumentation to prove single-photon generation and acquisition.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the collection website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In recent years, many groups and institutions have been committed to the research of integrated quantum photonic circuit technologies, of which the key components are waveguide coupled single photon sources. In this study, we propose an on-chip waveguide-coupled single photon source that is easily implemented as the waveguide is directly made from the quantum dot membrane. In order to scatter light out of the on-chip waveguide plane into the detection apparatus, grating output couplers are made at both ends of the waveguide. The photon statistics of the on-chip photon source were investigated by second-order correlation function g(2)(τ) measurements using a Hanbury Brown and Twiss interferometer. From the spectra and cross-correlation experiments by collecting emission at the point of quantum dot and out coupler, the emitting of single photons from the same quantum dot and propagating via the waveguide to the out couplers was confirmed. These results show that we have achieved an on-chip single photon source that is easily implemented and easily integrated into quantum photonic circuits. Full article
