This paper presents a four-context MEMS optically differential reconfigurable gate array that is useful in a space radiation environment. The technique enables rapid recovery of a programmable device that has been damaged by high-energy charged particles. It can use incorrect configuration data including some error bits resulting from damage by particles. This paper also clarifies the fault tolerance of the MEMS optically differential reconfigurable gate array.

Elasticoluminescence (ESL) is a kind of mechanoluminescence (ML). ESL materials are novel functional materials that can convert elastic deformation energy into visible light directly. Utilizing the materials, novel sensing devices and various applications are now under development. These materials can allow direct viewing of stress distribution.

Baile Zhang, G. Barbastathis
We calculate rigorously the optical forces on two interacting particles trapped in an optical vortex with helical phase front and demonstrate the dynamic process of the two particles' evolution. We show that in this two-particle system, a particle trapped by an optical vortex at one moment can be released due to the interaction from the other trapped particle in the next moment. To our best knowledge, this work is the first theoretical description on dynamic evolution of multiple particles trapped by an optical vortex.

We present the design of hollow near-field scanning microscope (NSOM) probe with nanogratings-on-tip to transport and concentrate localized surface plasmonic polariton (SPP) wave. By adding nano-grooves started from the intensity-maximum locations of lowest transmission mode and with pitch period supporting the metal-air interface SPP mode, the power throughput is increased at over 530 times comparing with single aperture probe with 405nm source and 100nm diameter aperture size. Two types of nanograting probe designs are chosen for fabrication and the power enhancement comparison is examined by probing the near-field fluorescent intensity of excited uniform quantum dots (QDs) layer via micro-contact printing method.

Quantum-dot lasers, first proposed by Arakawa and Sakaki of University of Tokyo in 1982 [1], are semiconductor lasers with nano-sized semiconductor particles called quantum dots as light sources. Self-assembled quantum dots emitting light of 1.3 µm was found in 1995 [2], and room-temperature continuous lasing was achieved at the wavelength in 1999[3]. Based on subsequent research achievements under industry-academia collaboration in Japan, QD Laser, Inc. [4] was launched to commercialize quantum-dot lasers, which have a variety of superior performance to conventional lasers like temperature insensitivity, high temperature operation, low-power consumption, low-cost mass production and SHG-based visible light lasing including green to realize mobile laser projectors. This talk will provide QD laser activity, i.e., the organization, applications & markets from optical communication to consumer electronics, self-assembled quantum-dot lasers, the product portfolio and the business model.

A liquid tunable lens with extended depth of focus (DOF) is presented. By integrating a rotational symmetric quartic function (QF) phase plate into the liquid lens' cavity, the lens can achieve higher tolerance to the defocus aberration. The liquid lens was fabricated through a convenient and low-cost process that combined single-point diamond turning (SPDT) with soft lithography using polydimethylsiloxane (PDMS). Experimental and theoretical results are in good agreement. Both focal length tunability and extended DOF have been demonstrated with the proposed liquid lens.

We present the performance of a piezo-actuated compliant micromirror made of single crystal silicon, which is assembled with a compliant displacement amplification mechanism made of copper. Both of those two parts are purely based on the elasticity and deformation of thin beams. The measurement results reveal that our optical device achieves the specified function as a linear optical scanner, and that the kinetic motion and out-of-plane bending are under control.
