Journal ArticleDOI
Ultracompact biochemical sensor built with two-dimensional photonic crystal microcavity.
TL;DR: By measuring the resonant wavelength of a two-dimensional photonic crystal microcavity, a time-resolved sensing capability is demonstrated that can detect the change in refractive index of 0.002.
Journal ArticleDOI
Enhanced fluorescence emission from quantum dots on a photonic crystal surface.
Nikhil Ganesh,Wei Zhang,Patrick C. Mathias,Edmond Chow,J. A. N. T. Soares,Viktor Malyarchuk,A. Smith,Brian T. Cunningham +7 more
TL;DR: Fluorescence intensity can be enhanced by a factor of up to 108 compared with quantum dots on an unpatterned surface by fabricating two-dimensional photonic crystal slabs that operate at visible wavelengths and engineering their leaky modes so that they overlap with the absorption and emission wavelengths.
Journal ArticleDOI
Three-dimensional control of light in a two-dimensional photonic crystal slab
Edmond Chow,Shawn-Yu Lin,Steven G. Johnson,Pierre R. Villeneuve,John D. Joannopoulos,Joel R. Wendt,Gregory A. Vawter,Walter J. Zubrzycki,Hong Q. Hou,A. Alleman +9 more
TL;DR: The fabrication of a waveguide-coupled photonic crystal slab with a strong 2D bandgap at wavelengths of about 1.5 µm is reported, which is capable of fully controlling light in all three dimensions and raises the prospect of being able to realize unusual photonic-crystal devices, such as thresholdless lasers.
Journal ArticleDOI
Application of plasmonic bowtie nanoantenna arrays for optical trapping, stacking, and sorting.
Brian J. Roxworthy,Kaspar D. Ko,Anup Kumar,Kin Hung Fung,Edmond Chow,Gang Logan Liu,Nicholas X. Fang,Kimani C. Toussaint +7 more
TL;DR: The use of low input power densities (power and NA) suggests that this bowtie nanoantenna trapping system will be particularly attractive for lab-on-a-chip technology or biological applications aimed at reducing specimen photodamage.
Proceedings ArticleDOI
Ultra compact biochemical sensor built with two dimensional photonic crystal microcavity
TL;DR: By measuring the resonant wavelength of a two-dimensional photonic crystal microcavity, Wang et al. as discussed by the authors detected the change in refractive index of 0.002 using water in 5% glycerol.
