Special Issue Information
Dear Colleagues,
Nowadays, advances in optical microcavities (MCs) are manifested in both fundamental and applied research, due to their high-quality factors and small mode volumes, which enable light–matter interactions to be significantly enhanced. Among the various recent developments in MCs, nonlinear photonics, quantum cavity electrodynamics, cavity optomechanics and microlasers stand out. However, MCs can be configured for a wide variety of chemical or biomolecular sensing applications. In addition, MCs can enhance light absorption in organic solar cells and significantly improve device performance. Moreover, the resonance effects of confined light in MCs can be used to increase the radiation pressure force of electromagnetic-wave-driven micromotors.
Radiation pressure has been used to manipulate micro-objects and biological organisms. Optical traps are based on the radiation pressure force resulting from photon momentum transfer; they involve early optical levitation configurations and optical tweezers. In recent years, a direct-acting micromechanical resonator was developed using only the force provided by radiation pressure. Furthermore, experimental evidence for radiation pressure in microcavity photonics has demonstrated that this structure is capable of self-oscillations and forced oscillations. In optomechanics, MCs usually use radiation pressure as a light–matter coupling mechanism and gradient optical force as a driving mechanism, which strongly depends on the magnitude of the resonator displacement and the laser intensity.
We are inviting researchers to contribute their latest research advances in microcavities and related phenomena, including newly emerging material systems with unique optical features, such as detallo-dielectric crystals, hybrid materials, high-index semiconducting materials, graphene membrane, etc.

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.
