Photonic bandgaps in patterned waveguides of silicon-rich silicon dioxide
Neal, R.T., Zoorob, M.E., Charlton, M.D., Parker, G.J., Finlayson, C.E. and Baumberg, J.J. (2004) Photonic bandgaps in patterned waveguides of silicon-rich silicon dioxide. Applied Physics Letters, 84, (13), 2415-2417. (doi:10.1063/1.1690106).
We describe waveguides of photoluminescent silicon-rich silicon dioxide, which have been patterned by triangular two-dimensional (2D) photonic crystals to give higher-order photonic bandgaps occurring within the luminescence band of the core material. Photonic crystal modification of the photoluminescence spectrum allows identification of angle-tuned photonic bandgaps, in close agreement with 2D plane wave expansion and finite-difference time domain simulations. We discuss the importance of these findings for the development of integrated optical circuitry based on silicon-compatible microelectronics.
