Guided-Wave Optical Biosensors
Guided-wave optical biosensors are reviewed in this paper. Advantages related to optical technologies are presented and integrated architectures are investigated in detail. Main classes of bio receptors and the most attractive optical transduction mechanisms are discussed. The possibility to use Mach-Zehnder and Young interferometers, microdisk and microring resonators, surface plasmon resonanc...
متن کاملReal-Time Detection of Staphylococcus Aureus Using Whispering Gallery Mode Optical Microdisks
Whispering Gallery Mode (WGM) microresonators have recently been studied as a means to achieve real-time label-free detection of biological targets such as virus particles, specific DNA sequences, or proteins. Due to their high quality (Q) factors, WGM resonators can be highly sensitive. A biosensor also needs to be selective, requiring proper functionalization of its surface with the appropria...
متن کاملImproved optical filter responses in cascaded InGaAsP/InP microdisk resonators
Waveguide-coupled microdisk and microring resonators as optical filters have been of great interest due to their high wavelength selectivity and ultra-compact sizes [1 – 4]. Recently, higher-order filters based on microring resonators with improved performances have been demonstrated in compound glass and AlGaAs/GaAs material systems [3, 4]. These higher-order filters show steeper rolloffs and ...

متن کاملWavelength- and Bandwidth-Tunable Filters Based on MEMS-actuated Microdisk Resonators λ1 Input Port Through Port
A wavelengthand bandwidthtunable filter with microelectromechanical-system (MEMS)actuated waveguides is first demonstrated on a silicon-based microdisk resonator. Integrated microheaters enabled wavelength tuning up to 125GHz. Bandwidth can be tuned from 12.0 to 41.2GHz by coupling control. © 2005 Optical Society of America OCIS codes: (130.3120) Integrated optics devices; (140.4780) Optical re...
