30 Years of Microoptics Conference [PDF]
2017 22nd Microoptics Conference (MOC), 2017 The 1st Microoptics Conference (MOC) was held in Tokyo on October 15–16, 1987. Since then, MOC is held every odd-numbered year in Japan sponsored by The Japan Society of Applied Physics (JSAP). From 2004, for possible even-numbered years, MOC has been held outside of Japan. Some MOCs were jointed or co-located with other conferences. In my today's talk,

Lithography-Free Technology for the Preparation of Digital Microfluidic (DMF) Lab-Chips with Droplet Actuation by Optoelectrowetting (OEW) [PDF]
International Journal of Analytical Chemistry, 2022 Electrically conducting liquid droplets can be activated and moved by electrowetting-on-dielectric (EWOD) and optoelectrowetting (OEW). An important application is droplet manipulation in digital microfluidics (DMF, lab-on-a-chip 2.0) as a chip-sized ...

Doped or Quantum-Dot Layers as In Situ Etch-Stop Indicators for III/V Semiconductor Reactive Ion Etching (RIE) Using Reflectance Anisotropy Spectroscopy (RAS) [PDF]
Micromachines, 2021 Reflectance anisotropy spectroscopy (RAS), which was originally invented to monitor epitaxial growth, can—as we have previously shown—also be used to monitor the reactive ion etching of III/V semiconductor samples in situ and in real time, as long as the

Two-dimensional photonic crystal polarizer [PDF]
Chin. Phys. Lett. 18, 1082 (2001), 1999 A novel polarizer made from two-dimensional photonic bandgap materials was demonstrated theoretically. This polarizer is fundamentally different from the conventinal ones. It can function in a wide frequency range with high performance and the size can be made very compact, which renders it useful as a micropolarizer in microoptics.

Fabrication of mirror templates in silica with micron-sized radii of curvature [PDF]
, 2016 We present the fabrication of exceptionally small-radius concave microoptics on fused silica substrates using CO2 laser ablation and subsequent reactive ion etching. The protocol yields on-axis near-Gaussian depressions with radius of curvature $\lesssim5$ microns at shallow depth and low surface roughness of 2 angstroms. This geometry is appealing for
