Special Issue 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 photon.

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 submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue 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 2300 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.

A current-assisted single-photon avalanche diode (CASPAD) is presented with a large and deep absorption volume combined with a small p-n junction in its middle to perform avalanche trigger detection. The absorption volume has a drift field that serves as a guiding mechanism to the photo-generated minority carriers by directing them toward the avalanche breakdown region of the p-n junction. This drift field is created by a majority current distribution in the thick (highly-resistive) epi-layer that is present because of an applied voltage bias between the p-anode of the avalanching region and the perimeter of the detector. A first CASPAD device fabricated in 350-nm CMOS shows functional operation for NIR (785-nm) photons; absorbed in a volume of 40 × 40 × 14 μm3. The CASPAD is characterized for its photon-detection probability (PDP), timing jitter, dark-count rate (DCR), and after pulsing. Full article
