We report the use of digital signal processing (DSP) strategies to realize high-sensitivity on-chip fluorescence detection in microfluidic-opto-electronic printed circuit board (PCB) devices without requiring bulky high-quality optical components and filters. An isotachophoresis (ITP) assay was studied in a microfluidic PCB with an embedded standard complementary metal oxide semiconductor sensor array...
We demonstrate three-dimensional simulation of a third order silicon-based grating with full-width-half-maximum (FWHM) reflection bandwidth of 4nm. This provides more than 2 orders of magnitude improvement over a conventional side-walled grating structure. The relationship of grating performance over the infra-red wavelength range is also presented.
We demonstrate two- and full three-dimensional simulation of an active silicon-based photonic crystal chromatic dispersion compensator with low power consumption of 114nW and functioning at 40.5MHz. The novel device allows waveguiding and electrical transport to be individually tailored to a large extent.
In this work, we demonstrate two- and three-dimensional (3D) simulations of an active silicon-based photonic crystal chromatic dispersion compensator utilizing the free carrier dispersion effect. The device has a low power consumption of 114nW and its intrinsic device modulation speed is predicted to function at 40.5MHz. Due to the device architecture, simulation must be carried out in 3D so as to...
Summary form only given. A new method of post-growth intermixing of GaAs-AlGaAs multiple quantum wells (MQWs) has been developed. This new technique of impurity-free vacancy induced disordering is area-selective, very reliabile and high reproducible. The surface of the sample is coated with a thin film of spin-on-glass (silicon oxide) and pre-baked for 30 min, at 4000/spl deg/C. Rapid thermal annealing...
