Special Issue Information

Dear Colleagues,

The recent advances in the field of optical diffraction, imaging, and display have led to a remarkable evolution in optics and photonics, driven by the increasing demand for precise and efficient light modulation and emission in various applications, e.g., holography, imaging, laser beam shaping, optical communications, virtual reality and augmented reality, etc. Optical diffraction for achieving precision control over the phase and amplitude of light enables the compact and flexible design of optical systems such as diffractive optical elements (DOEs), spatial light modulators, metasurfaces, perfect lenses, and photonic crystals, contributing to high-performance imaging and display systems. With ongoing research in theory, design, fabrication, and testing, significant progress has been made in understanding the transformation of light as it emits, propagates, or diffracts, leading to the wide development of structured laser beams, wavefront sensors, holography, microdisplays, nanolithography, biomedical imaging, and optical data transmission applications.

This Special Issue invites you to present state-of-the-art articles on theoretical insights, experimental breakthroughs, and exciting applications in diffraction optics, imaging, and display. Topics include, but are not limited to, the following:

  • Diffraction optical elements (DOEs);
  • Meta-surfaces for imaging and display;
  • Virtual reality and augmented reality;
  • Nano-photonics and nanolithography;
  • Holography and Fourier optics;
  • Metamaterials;
  • Light scattering;
  • Phase modulation and laser beam shaping;
  • Wavefront sensing;
  • Optical microscopy; differential interference contrast (DIC) microscope;
  • Coherent diffraction imaging/phase contrast imaging/computational imaging.

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).

Compared with conventional detectors, a circularly polarized detector operating at 4.26 μm effectively suppresses background noise (e.g., solar scattering and atmospheric interference), enabling high-precision CO2 monitoring across ecosystems like farmland, forests, and wetlands. This capability allows the precise quantification of carbon sink potential and ecosystem health. Our design employs a mid-wave HgCdTe detector—a well-established platform—combined with a CMOS-compatible Si/SiO2 metasurface. Geometric displacements were applied to break C2 symmetry, achieving a chiral design. Through multiparameter optimization, we realized a circularly polarized photodetector (CPPD) with a CPER of 18 dB, expected to demonstrate superior CO2 monitoring performance. These advances may offer researchers and practitioners a robust tool for both fundamental studies and field deployments. Full article
