There is a need to develop mid-infrared (IR) spectrometers for applications in which the absorbance of only a few vibrational mode (optical) frequencies needs to be recorded; unfortunately, there are limited alternatives for the same. The key requirement is the development of a means to discretely access a small set of spectral positions from the wideband… (More)
This demo presents Wikiglass, a learning analytic tool for visualizing the statistics and timelines of collaborative Wikis built by secondary school students during their group project in inquiry-based learning. The tool adopts a modular structure for the flexibility of reuse with different data sources. The client side is built with the… (More)
This paper reviews state-of-the art dense wavelength-division multiplexing demultiplexers (DWDM) for commercial deployment in high-capacity optical networks. Fiber-optic component technologies, features, designs, and performance are compared for various network applications.
