Abstract

Summary form only given.We show clear evidence that photonic crystals (PC) can be used in ultrasmall integrated optics to cascade two elements, in this case a cavity and a waveguide. We use as a basis PC a triangular array of holes of period a=220-260 nm etched through an AlGaAs planar waveguide, in which we define a hexagonal cavity of side h=7a (H7 cavity), and a guide with width varying from a to 4a and a length of 36a. Variable coupling is achieved by bringing both elements within N=2 to 5 PC rows of each other.
