For applications in light modulation, biosensing and optical non-linearities on a silicon photonic platform, it is often advantageous to guide the modal power in the lower index cladding material whose properties are tailored for that particular application[ 1,2]. A convenient way of integrating such a scheme is the use of silicon slot waveguides, where two parallel rails, separated by a lower index...
We report measurement of the group index dispersion of the supermodes of a three channel array of strongly coupled silicon-on-insulator waveguides, and compare results with numerical simulations. We observe strong coupling-induced dispersion.
A full description of the synthesis process for chirped and apodized integrated Bragg gratings is presented. Starting from a target complex reflectivity, the local Bragg and coupling coefficients are extracted and converted into physical grating parameters. Control over both the amplitude and group delay profiles of the devices may be exerted using a tapered sidewall relief grating design. Example...
The authors report on the study of propagation losses in engineered slow light photonic crystal (PhC) waveguides. By modifying the rows of holes adjacent to the defect, it has been shown that dispersion can be reduced to manageable levels, enabling promising applications, such as optical buffers and for increasing light matter interactions. Loss then remains as the key issue facing slow light photonic...
