Due to recent advances in low-power VLSI design technology, it has become feasible to
power portable or remote electronic devices by scavenging the ambient energy. The design …

We present a large-range and high-precision autofocus method based on an annular
diffractive optical element (DOE) for a laser direct writing system. By analyzing the shape of …

We compare THz emission properties of rectangular, circular, and diabolo spintronic
antennas composed of 2 nm Fe and 3 nm Pt layers on MgO substrates. Although the …

An efficient nonlinear photodetector (NLPD) is demonstrated with quadratic response based
on a few‐layer InSe p–n homojunction, which is beneficial from the strong second harmonic …

We investigate the interaction of highly focused linearly polarized optical beams with a metal
knife-edge both theoretically and experimentally. A high numerical aperture objective …

A new 3D micro-nano integrated M-shaped carbon nanotube (CNT) architecture was
designed and fabricated. It is based on vertically aligned carbon nanotube arrays composed …

The spatial structure of a tightly focused light field is measured with a double knife-edge
scanning method. The measurement method is based on the use of a high-quality double …

This paper describes an analytical model for the well-known optical knife-edge
displacement sensor that predicts the relationship between the knife-edge displacement and …

The synthesis of single-walled carbon nanotubes (SWCNTs) on a transparent substrate with
multiple-catalyst layer (Fe/Al/Cr: 0.5/15/500nm) using laser-induced chemical vapor …

Driven by global energy conservation, carbon reduction and green environmental protection
issues, the recyclable thermoplastic carbon fiber composites gradually replace …
