Special Issue Information

Dear Colleagues,

Photonics is the engineering of light. Photonic microsystems combine light, electronics, and micro- and nanotechnologies in an ideal manner. The advent of lithography technologies, developed in the early 1970s, provided new opportunities for micro-optics as we know it today, including binary and multi-level optics. Another essential technology for photonic microsystems is that of light sources, these are most often laser diodes or LEDs. Closely coupled to the development of laser diodes, is the technology of the optical fiber, which is relevant for photonic microsystems. Finally, an umbrella technology with relevance for photonics is that of MEMS (micro-electromechanical systems) where optical functionality began to appear in the early 1990s, leading to optical MEMS and MOEMS (micro-opto-electro-mechanical systems). More recently, the development of metamaterials where novel electronic and photonic properties derive from microscale to mesoscale interactions and phenomena, has enabled novel structures, devices, and systems.

The present Special Issue on « Photonic Microsystems » will be a forum for scientists, who are harnessing light, or photons, and control its propagation phenomena via interaction with produced structures at the micro- and nano-scale. This leads to diverse applications in technology fields such as imaging, communication, sensing, and instrumentation, as well as sciences such as biology and medicine, chemistry, and fundamental physics. This Special Issue will cover a broad range of topics from the field, including but not limited to the following :

  • Free-space and guided-wave micro-optics
  • The optical scanners and micromirrors
  • Adaptative optics
  • Micro-optical systems for imaging
  • Microactuators for photonic devices
  • Adaptative and tunable micro-photonics
  • Telecom devices
  • Spatial light modulators
  • Optofluidics
  • Microspectrometers
  • MOEMs sensors
  • Cavity optomechanics
  • Nanophotonics including nanoplasmonics, metamaterials, and metasurfaces
  • Micro- and nano-photonic displays
  • Silicon photonics
  • Nanoscale sources and emitters
  • Photonic crystals
  • Quantum photonic devices
  • Micro- and nano-biophotonics

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. Photonics is an international peer-reviewed open access monthly 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 2400 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

This contribution presents an overview of advances in scanning micromirrors based on MEMS (Micro-electro-mechanical systems) technologies to achieve beam scanning for OCT (Optical Coherence Tomography). The use of MEMS scanners for miniaturized OCT probes requires appropriate optical architectures. Their design involves a suitable actuation mechanism and an adapted imaging scheme in terms of achievable scan range, scan speed, low power consumption, and acceptable size of the OCT probe. The electrostatic, electromagnetic, and electrothermal actuation techniques are discussed here as well as the requirements that drive the design and fabrication of functional OCT probes. Each actuation mechanism is illustrated by examples of miniature OCT probes demonstrating the effectiveness of in vivo bioimaging. Finally, the design issues are discussed to permit users to select an OCT scanner that is adapted to their specific imaging needs. Full article
