Photonic crystal cavities in silicon dioxide
نویسندگان
چکیده
One dimensional nanobeam photonic crystal cavities fabricated in silicon dioxide are considered in both simulation and experiment. Quality factors of over 104 are found via simulation, while quality factors of over 5 103 are found in experiment, for cavities with mode volumes of 2.0 /n 3 and in the visible wavelength range 600–716 nm. The dependences of the cavity quality factor and mode volume for different design parameters are also considered. © 2010 American Institute of Physics. doi:10.1063/1.3297877

Optical field enhancement factor of Silicon and indium phosphide nano-cavities
Nano cavities based on silicon and indium phosphide materials have been comparedin this study, considering field intensity enhancement factor. The results of FDTD based simulations declare that the Si nano-cavity improves confined optical field about 7.7 times higher than the InP based nano-cavity. The introduced dielectric nano-cavities support resonance wavelength at about λ=1.55 μm.

We present a comparison of high Q-factor tapered membrane-type onedimensional photonic crystal micro-cavities embedded in photonic wire waveguides based on silicon-on-insulator (SOI). Q-factor values as large as 24,000 have been measured, together with normalized transmission of 67%: an improvement in the Q-factor value in comparison with previous results obtained on structures with silicon cor...
