Dear Colleagues,

Light detection and ranging (LiDAR) sensors have attracted significant research interest for various applications, such as advanced driver assistance systems (ADAS), autonomous vehicles, robots, drones, mobile phones, etc. In particular, cost-effective and compact LiDAR sensors become essential for the development of these applications. Nonetheless, current LiDAR sensors require a mechanical scanning system and can thus hardly satisfy their stringent requirements. Hence, solid-state LiDAR sensors based upon semiconductors have recently been paid a great deal of attention as a key solution.

Single-photon avalanche diodes (SPADs), silicon photomultipliers (SiPMs), and avalanche photodiodes (APDs) especially based on standard CMOS technologies are considered the most crucial devices for solid-state LiDAR sensors because they are able to not only detect very low-intensity signals but also provide cost-effectiveness and high-volume manufacturing as CMOS is a universal platform. Recent advances in the fields of CMOS-based SPADs/SiPMs/APDs can certainly facilitate the realization and development of cost-effective and compact solid-state LiDAR sensors.

The goal of this Special Issue is to invite to the submission of high-quality, state-of-the-art research articles that deal with challenging issues in solid-state LiDAR sensors. We solicit original papers of unpublished and completed research that are not currently under review elsewhere. Topics of interest include but are not limited to:

• Single-photon avalanche photodiodes (SPADs) in CMOS technologies;
• III-V SPADs for solid-state LiDAR sensors;
• Silicon photomultipliers (SiPMs);
• Avalanche photodiodes (APDs);
• Simulation and modeling of SPADs/SiPMs/APDs;
• Analog front-end (AFE) circuits for LiDAR sensors;
• Readout integrated circuit (ROIC) for LiDAR sensors;
• Solid-state LiDAR systems.

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. Sensors 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 2600 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.
