Advances and Applications of Grating

Dear Colleagues,

Grating is a crucial component for manufacturing, metrology, and scientific instruments. With the advantages of excellent stability to environmental changes, grating has already played a pivotal role in the beginning of the era of atomic-level manufacturing. On the flip side, the quality and performance of grating have been greatly improved by the development in extreme manufacturing and nanometrology. We are confident and expect innovations and breakthroughs in the field of grating from the new revolution of the manufacturing paradigm.

With a long history of over 200 years, the feature of periodic structure remains, but grating is constantly developing. In recent years, we created several new gratings, such as planar grating, volume phase grating, and even meta-grating. We used several manufacturing approaches for better gratings, such as interferometry and laser/e-beam direct writing. We proposed several methods to calibrate gratings, from diffractometers to nanometer comparators. We invented plenty of grating-based systems for spectrometers, optical encoders, laser systems, and other applications. We also established the grating as a photonic device by MOEMS techniques, making it more than an optics component.

This Special Issue aims to present an overview of the state-of-the-art research related to the advances and applications of grating, including the design, manufacturing, metrology, and application of all kinds of gratings. We welcome comprehensive and visionary research and review articles. We cordially invite researchers to submit their contributions to this Special Issue.

Topics include, but are not limited to, the following:

• Design and simulation of gratings.
• Manufacturing approach, equipment, and process of gratings.
• Test and calibration model, method, and device of gratings.
• Various applications of gratings.
• Novel kinds of gratings such as meta-grating and MOEMS grating.
