We report a new design and fabrication of parylene-hinged electrostatic optical scanner made by the SOI-MEMS process technology. Parylene is a CVD-processed organic material of small elastic constant and high chemical stability, and it was found to be suitable to make a low-voltage MEMS scanner of low resonance frequency.

A system capable of both two-dimensional lateral positioning and focusing of a liquid micro-lens for variable fiber coupling is presented. Lateral positioning and focus adjustment is accomplished by electrowetting-on-dielectrics. The chip is fabricated on a transparent Pyrex substrate and is equipped with a two dimensional array of electrodes featuring a well-defined microstructure which allows accurate positioning of the liquid micro-lens. The system is used as a variable optical fiber coupling element, and measurements of optical power coupled to a fiber as a function of the applied voltage are presented. Applications such as adaptive wave front sensing, optical tweezers, or three- dimensional focus control for microscopy are envisaged.

The paper is about emerging technologies enabled by nanophotonics to combat climate change. We developed and demonstrated 1.) nanocrystal hybridized white light sources and those also embedded with plasmonic metal nanoparticles for the reduction of global energy consumption, 2.) photovoltaic nanocrystal scintillators hybridized on solar cells for the generation of efficient green energy sources, and 3.) photocatalytic nanoparticle and nanocomposite systems for massive environmental decontamination, all to contribute to the reduction of greenhouse gas amount.

Next-generation infra-red astronomical instrumentation for space and ground-based telescopes requires MOEMS-based programmable slit masks for multi-object spectroscopy (MOS) usable in a cryogenic environment. A 100x200 mum2 micro-mirror array was successfully designed, fabricated and tested, with tilting angle of 20deg at 100 V. In parallel we have developed and implemented a high-resolution Twyman-Green interferometer and a cryo-chamber for full surface and operation characterization. The micromirrors could be successfully actuated before, during and after cryogenic cooling. Surface deformation of gold coated mirrors at 300 K and below 100 K shows a slight increase from 35 nm to 50 nm PtV, still well suited for MOS application.

This paper present a six port PCWG channel created from a circular photonic crystal array (CPC) with filtering functions. PC based waveguide (PCWG) created along the radial direction of CPC enables the transmission of lightwaves in subwavelength width structures. Additional filter rods are added to the PCWG to server as filtering function so that only allowed lightwaves with designated frequency can pass through the rods set. The other frequencies will be reflected. This PC device allow the distribution of light for different frequencies to different output port channel, which is very useful for multiplexing optical circuit and system.
