Slotted Photonic Crystal Sensors
Optical biosensors are increasingly being considered for lab-on-a-chip applications due to their benefits such as small size, biocompatibility, passive behaviour and lack of the need for fluorescent labels. The light guiding mechanisms used by many of them results in poor overlap of the optical field with the target molecules, reducing the maximum sensitivity achievable. This review article pre...
متن کاملSuperradiance for Atoms Trapped along a Photonic Crystal Waveguide.
We report observations of superradiance for atoms trapped in the near field of a photonic crystal waveguide (PCW). By fabricating the PCW with a band edge near the D(1) transition of atomic cesium, strong interaction is achieved between trapped atoms and guided-mode photons. Following short-pulse excitation, we record the decay of guided-mode emission and find a superradiant emission rate scali...
متن کاملEfficient computation of photonic crystal waveguide modes with dispersive material.
The optimization of PhC waveguides is a key issue for successfully designing PhC devices. Since this design task is computationally expensive, efficient methods are demanded. The available codes for computing photonic bands are also applied to PhC waveguides. They are reliable but not very efficient, which is even more pronounced for dispersive material. We present a method based on higher orde...
متن کاملPlanar photonic crystal waveguide biosensor
We present protein detection using a planar photonic crystal waveguide sensor. Experimental results of refractive index measurements show good agreement with simulations. The sensor has been used for protein detection and showed successful detection with excellent signal to noise ratio of proteins with concentrations around 10 μg/ml (0.15μMolar). Introduction In the past 20 years, the research...
متن کاملApodized photonic crystal waveguide gratings.
Apodized photonic crystal (PC) waveguide gratings are proposed to suppress sidelobes which appear in reflection spectra of usual PC waveguide gratings. By using specific functions (Gauss and Gauss-cosine functions) for the longitudinal refractive index distribution, it is possible to suppress sidelobes in the reflection spectra of PC waveguide gratings efficiently. The apodization is realized b...
