Development of the in vivo flow cytometer
… laser beam is focused by a cylindrical lens to a slit of light that is then demagnified and focused across a blood vessel by an achromat and microscope objective. Fluorescent cells are excited one by one as they flow through the excitation laser light slit, creating a burst of fluorescence whose …

Plasmonic devices for manipulating light at the nanoscale: slow-light waveguides and compact couplers
… I also introduce compact wavelength-scale slit-based structures for coupling free space light into MDM subwavelength plasmonic waveguides. I first show that for a single slit structure the coupling efficiency is limited by a trade-off between the light power coupled into the slit, and the …

Surface plasmons for enhanced metal-semiconductor-metal photodetectors
… employing metal nano-gratings and sub-wavelength slits. Various metal nano-gratings are designed on top of the gold fingers of an MSM-PD based on gallium arsenide (GaAs) for an operating wavelength of 830 nm to create SPP-enhanced MSM-PDs. Both the geometry and light absorption near the designed …

Achieving Complex Motion with Fundamental Components for Lamina Emergent Mechanisms
<p>Designing mechanical products in a competitive environment can present unique challenges, and designers constantly search for innovative ways to increase efficiency. One way to save space and reduce cost is to use ortho-planar compliant mechanisms which can be made from sheets of material, or …
