Transmission of slow light through photonic crystal waveguide bends.
The spectral dependence of the bending loss of cascaded 60 degrees bends in photonic crystal (PhC) waveguides is explored in a slab-type silicon-on-insulator system. An ultralow bending loss of (0.05 +/- 0.03) dB/bend is measured at wavelengths corresponding to the nearly dispersionless transmission regime. In contrast, the PhC bend is found to become completely opaque for wavelengths correspon...
متن کاملBound states in photonic crystal waveguides and waveguide bends
We investigate the mechanism for the appearance of bound states in two-dimensional photonic crystal waveguides and contrast it with the corresponding mechanism for conventional guides. It is shown that the periodicity of the photonic crystal can give rise to frequency ranges above cutoff where no guided modes exist in the waveguides. Such mode gaps make possible the creation of bound states in ...
متن کاملExperimental investigation of photonic crystal waveguide devices and line-defect waveguide bends
Photonic crystal waveguide devices incorporating line-defect waveguide bends have been fabricated. In this paper we present preliminary experimental analysis of these structures. Although evidence of photonic band-gap effects are observed in the spectra, transmission efficiency was found to be extremely low due to significant up-scattering losses from the holes. In order to quantify this loss m...
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...
