The dispersion of line-defect modes in silicon-on-insulator photonic crystal waveguides is explored by means of angle- and polarization-resolved micro-reflectance measurements. The frequency-wave vector range accessible to the experiments is greatly expanded by the use of attenuated total reflectance, in addition to the standard one, thereby allowing one to study both truly guided (evanescent) and quasi-guided (radiative) photonic modes. The presence of a supercell repetition in the direction…

Measurement of photonic mode dispersion and linewidths in silicon-on-insulator photonic crystal slabs
TLDR
The measured dispersion of photonic modes in one- and two-dimensional patterned silicon-on-insulator (SOI) waveguides is in very good agreement with full three-dimensional calculations based on expansion on the waveguide modes, indicating that a deep understanding of the propagation properties of patterned SOI waveguide is achieved.
Cavity modes in one-dimensional photonic crystal slabs
A theoretical study of cavity modes in one-dimensional photonic crystal slabs embedded in Silicon-on-Insulator structures is reported. Three different methods are employed, namely a guided-mode
k-space spectroscopy of photonic crystal slabs
In this work we show how the dispersion relation of slab-type PhCs can be directly determined both in the radiative and guided mode regimes by means of k-space spectroscopy. Angle-resolved

Probing the guided modes of a 2D photonic crystal slab using attenuated total reflectance
Photonic crystals (PhC) are of special interest in the applications of linear and non-linear optics, as the dispersion of light inside these periodic structures is strongly modified. In this thesis,
Exciton‐polaritons and nanoscale cavities in photonic crystal slabs
Recent theoretical work on exciton–light coupling in waveguide‐embedded photonic crystals is reviewed. After a short description of the theory of photonic crystal slabs, the following issues are

Extremely large group-velocity dispersion of line-defect waveguides in photonic crystal slabs.
TLDR
Waveguiding characteristics and group-velocity dispersion of line defects in photonic crystal slabs as a function of defect widths reveal that they can be tuned by controlling the defect width, and the results agree well with theoretical calculations, indicating that light paths with made-to-order dispersion can be designed.

TLDR
The combination of an efficient two-stage coupling scheme and utilization of ultra-long (up to 2mm) photonic crystal waveguides reduces the uncertainty in determining the loss figure to 3dB/cm.
