Abstract

The Finite Difference Time Domain method is applied to the bandwidth calculation of a nanostructure known as PBG Air Bridge filter, which is formed by a semiconductor slab waveguide and an array of air holes. Its transmittance spectrum is calculated by the FFT of electromagnetic fields propagating in the structure. Results show that structures made of circular holes can be used in a CWDM grid between 1470 and 1610 nm. It is shown that up to eight wavelengths may be inserted in this region, limited by the large bandwidth of such devices.
