Micromachines, Vol 12, Iss 4, p 378 (2021)
Microelectromechanical System (MEMS)-based scanning mirrors are important optical devices that have been employed in many fields as a low-cost and miniaturized solution. In recent years, the rapid development of Light Detection and Ranging (LiDAR) ha

Residual stress is one of the key factors that directly determines the optical quality of micro-optical devices. With the same residual stress, the larger the aperture is, the worse the optical quality is. Therefore, continuous micromirrors are more

We describe a tunable Fabry–Perot filter and grating hybrid modulator to achieve a higher spectral resolution compared with that produced by a single grating with the same period. In the hybrid modulator, a tunable Fabry–Perot filter is designed

By investigating the transmittance and phase characteristics of the square holes on the metallic film, we find that the transmittance fluctuates with center distance between holes and appears resonant peaks, which attributes to the surface wave enhan

An integration method of grating array with different periods and Fabry-Perot (FP) resonator with an all-dielectric singlecavity is proposed. It is based on the capacity of spatial separation of spectral component by the grating and band-pass charact

A structured lens with a large numerical aperture for high diffraction efficiency is proposed. This structured lens is formed by varying high-refractive-index-dielectric (HRID) square holes in a metallic film. Compared with previous structured lenses

We present a new design for the integration of a tunable Fabry-Perot (FP) filter and the grating etched on top of the cavity (IGFP) in the miniature spectrometer. It is based on the predispersion of the grating with the capacity of spatial separation

A graded photonic crystal formed by varying the high-refractive-index square dielectric rods is used as a structured lens to focus. This lens can realize high energy efficiency and large numerical aperture. Otherwise, the energy efficiency and the im

A multiple beams combiner based on three-dimensional (3D) isotropic near-zero index metamaterials (NZIM) is proposed. Built on the Snell's law, the combination of multiple beams can be readily realized via NZIM and further validated by numerical fini

A method is brought forward for realizing polarization dependent devices by employing sub-wavelength asymmetrical hole array on a metallic film. Based on the fundamental mode approximation, the phase retardations of rectangular hole for two orthogona
