Comparison of local and global computation and its implications for the role of optical interconnections in future nanoelectronic systems
(Elsevier, 1993)Various methods of simulating diffusion phenomena with parallel hardware are discussed. In particular methods are compared requiring local and global communication among the processors in terms of total computation time. ... -
Experimental demonstration of highly confined photonic crystal based waveguides
(IEEE, 2001)The bending and guiding of the electromagnetic (EM) waves in highly confined waveguides was demonstrated. The electromagnetic waves were constructed by removing a single rod from a perfect three layer-by-layer photonic ... -
Fabrication of high-speed resonant cavity enhanced schottky photodiodes
(Institute of Electrical and Electronics Engineers, 1997-05)We report the fabrication and testing of a GaAs-based high-speed resonant cavity enhanced (RCE) Schottky photodiode. The top-illuminated RCE detector is constructed by integrating a Schottky contact, a thin absorption ... -
Filtering characteristics of hybrid integrated polymer and compound semiconductor waveguides
(IEEE, 2002)This paper reports a study on a compact filter fabricated using hybrid integration of compound semiconductors and polymers. A GaAs epilayer is glued onto a polymer channel waveguide forming a highly asymmetrical directional ... -
High efficiency monolithic photodetectors for integrated optoelectronics in the near infrared
(IEEE, 2009)Monolithic Germanium photodetectors integrated on Si with external efficiency up to 68% at 1550nm and low dark current density 3.2mA/cm2 are demonstrated. The absorption edge red shifted by 47nm corresponding to bandgap ... -
Novel integrated optical displacement sensor for scanning force microscopies
(IEEE, 2003)A novel displacement sensor for scanning force microscoples using an integrated optical micro-ring resonator is described. Device operates by monitoring the changes in transmission spectrum of micro-ring resonator. This ... -
Pressure sensing using micromachined asymmetric integrated vertical coupler
(IEEE, 2003)Analysis of a novel pressure sensor based on a SOI asymmetric vertical coupler is presented. The integrated optical component is a coupler composed of a single mode low index waveguide and a thin silicon slab. -
Scalable wavelength-converting crossbar switches
(IEEE, 2004-10)We report scalable low-power wavelength-converting Crossbar switches that monolithically integrate two-dimensional compact arrays of surface-normal photodiodes with quantum-well waveguide modulators. We demonstrate ... -
Self-aligning planarization and passivation for integration applications in III-V semiconductor devices
(IEEE, 2005)This paper reports an easy planarization and passivation approach for the integration of III-V semiconductor devices. Vertically etched III-V semiconductor devices typically require sidewall passivation to suppress leakage ...
