Electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals using a Michelson interferometer
Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
متن کاملBiosensing microsystem platform based on the integration of Si Mach-Zehnder interferometer, microfluidics and grating couplers
We have achieved the design, fabrication and packaging of microfluidic networks with photonic sensors for novel labon-chip platforms which incorporate the on-chip biosensing detection. As sensors, we used an integrated Mach-Zehnder interferometer (MZI) based on TIR waveguides (Si/SiO2/Si3N4) of micro/nanodimensions for evanescent field detection of biomolecular interactions onto the sensing are...
متن کاملNanoporous Polymeric Grating-based Optical Biosensors (preprint)
This paper demonstrates a label-free biological sensing method usmg nanoporous polymer gratings. The high index modulation (0.07) of the nanoporous polymer grating structure generates a high signal-to-noise ratio, making the structure an ideal label-free biodetection platform. The fabrication process of the nanoporous polymeric grating involves holographic interference patterning and a function...
متن کاملMiniature lamellar grating interferometer based on silicon technology.
We present a lamellar grating interferometer realized with microelectromechanical system technology. It is used as a time-scanning Fourier-transform spectrometer. The motion is carried out by an electrostatic comb drive actuator fabricated by silicon micromachining, particularly by silicon-on-insulator technology. For the first time to our knowledge, we measure the spectrum of an extended white...
متن کاملConducting polymer based electrochemical biosensors.
Conducting polymer (CP)-based electrochemical biosensors have gained great attention as such biosensor platforms are easy and cost-effective to fabricate, and provide a direct electrical readout for the presence of biological analytes with high sensitivity and selectivity. CP materials themselves are both sensing elements and transducers of the biological recognition event at the same time, sim...
