Fabrication and characterization of ZnSnxGe1GêÆxN2 alloys for light absorbers
2015 Edition, June 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The II-IV-nitrides are an alloy series analogous to the well-characterized III-nitrides, where a Group II and Group IV element replace the Group III element. We report on the fabrication and structural and optoelectronic characterization of...

Metallic Metasurfaces for Light Absorbers
2017 Edition, Volume 29, January 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Multi-band light perfect absorption by all-metal resonant structure is of particular interest for applications in a wide variety of technologies. Here, we propose and demonstrate a new strategy for achieving multi-band light absorber based on...

Color light sensor device for light absorbance measurement device
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

UV-spectrophotometer is light absorbance measurement device. It is used to measure the solution for checking the concentration. However, it is very expensive. This is a problem for the chemical education which doesn't have this device enough for every student. It...

Green laser annealing with light absorber
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

To compensate deep penetration depth of green laser light into Si, metal absorber was formed on a specimen. TiN absorber was effective to reduce necessary laser energy density to activate dopant, however Mo worked oppositely. In addition, specimens with the...

The design of a fuzzy-based light absorbance measurement device for chemical education is proposed in this paper. It is developed for supporting the chemical education which the device is not enough for every student. The proposed device measures the...

Tuning Simple Light Absorber of Fabry-Perot-Like Resonator
2017 Edition, July 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a plasmonic absorber of Fabry-Perot-like resonator and demonstrate the tuning capability of its spectral response. The conventional resonator comprises two spaced layers of gold to act as a confinement for the light and resonant...

Photothermal Switching Based on Silicon Mach–Zehnder Interferometer Integrated With Light Absorber
2016 Edition, Volume 8, April 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present an all-optical switch based on photothermal effects in a silicon Mach-Zehnder interferometer (MZI) integrated with a light absorber. The metal-insulator-metal light absorber located near the longer arm of the asymmetric MZI efficiently converts infrared...

Broadband light absorber based on one-dimensional gratings in semiconductor films
2013 Edition, September 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We design and fabricate a light absorber based on one-dimensional gratings in amorphous Si. We obtain high theoretical and experimental absorption in unpolarized light over wide wavelength and angular ranges.

Ultra-Broadband Super Light Absorber Based on Multi-Sized Tapered Hyperbolic Metamaterial Waveguide Arrays
2015 Edition, Volume 33, September 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose an ultra-broadband super light absorber by integrating different-sized tapered hyperbolic metamaterial (HMM) waveguides, each of which has a different and wide absorption band due to broadband slow-light response, into a unit cell. We numerically...

Design of a measurement device explaining the relationship between the concentration of solution and the light absorbance for chemical education
2016 Edition, June 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This research aims to study about developing and demonstrating the low-cost and portable light absorbance measurement device for using and learning in analytical experiments. The spectrophotometer is important for analytical chemistry to measure the...
