Paper published in Optica chosen as cover image

BiOpticaCoverNov2014_11-14ng’s research into metamaterial polarizers was published in Optica today. The micrograph of the device was chosen for the cover image of the November issue of Optica. The paper describes a linear polarizer that shows a transmission efficiency of ~74%. This is achieved by allowing one polarization to transmit unperturbed, while the orthogonal polarization is rotated by 90 degrees.

Congratulations to Xiaowen & Bing!

Xiaowen’s research into new diffractive lenses was published in JOSA A today and can be seen here. This paper describes an approach to design diffractive lenses with sharper mainlobes. Bing is also an author on this article. Congratulations to both!

Congratulations to Bing & Peng

Bing and Peng’s work in metamaterial couplers was published in Optics Express. The paper is titled, “Integrated metamaterials for efficient and compact free-space-to-waveguide coupling” and is available via open access here. Here, we show experimentally the most efficient, compact and versatile free-space-to-waveguide couplers. These are one of the most important passive devices in integrated photonics.

Congratulations to Nabil and Peng!

Nabil’s research on solar concentrators was recently published in Optics Express. He along with Peng showed that one can use the polychromat to spectrally split and concentrate sunlight into 3 distinct bands and absorb these bands using 3 different solar cells to achieve an overall increase in efficiency of more than 35%! The paper is open access here.
