“…This argument must also take account of the fact that`classicala waveguides can show curvature losses reduced to`negligible levelsa for 3 m radius curves [51], and exhibit very high scattering losses when narrow [51], due to the high index contrast. This result begs two controversial questions: (a) why do we need photonic crystal waveguides if we can realise tight bends without them, and (b) considering that the scattering loss for the high-index classical waveguides is large, why should photonic crystal waveguides that are an order of magnitude narrower, not su!er from the same loss?…”

“…1, we show a schematic of the waveguide studied. It was fabricated using the traditional sputtering and optical lithographic methods [14,15]. The rectangular core region is composed of a compound Ta 2 O 5 / SiO 2 glass of index of n=1.65.…”

“…They are used in optoelectronics as high Q resonators for wavelength division multiplexing. 4 For elastic waves, there are some early calculations on infinite long cylinders. 5,6 In those studies, the resonant modes appearing in infinite long cylinders were studied analytically and numerically.…”
