AbstractWe demonstrate a novel SOI-based photonic crystal(PC) double-heterostructure slot waveguide microcavity constructed by cascading three PC slot waveguides with different slot widths, and simulate the luminescence enhancement of sol-gel Erdoped SiO2 filled in the microcavity by finite-difference time-domain(FDTD) method. The calculated results indicate that a unique sharp resonant peak dominates in the spectrum at the expected telecommunication wavelength of1.5509μm, with very high normalized peak intensity of~108. The electromagnetic field of the resonant mode exhibits the strongest in the microcavity, and decays rapidly to zero along both sides, which means that the resonant mode field is well confined in the microcavity. The simulation results fully verify the enhancement of luminescence by PC double-heterostructure slot waveguide microcavity theoretically, which is a promising way to realize the high-efficiency luminescence of Si-based materials.?2011 Tianjin University of Technology and Springer-Verlag Berlin Heidelberg.
