Abstract :
The authors demonstrate a new way to design ultra-compact microwave channelizers by the combination of different types of lattices and properties of photonic crystals (PhCs). The authors also present and experimentally validate sensitive displacement tunable filters based on the guided resonance of PhCs. PhCs offer the opportunity to construct ultra-small integrated circuits to overcome the limitations of integrated electric circuits. In this talk, the authors experimentally demonstrate hybrid lattice PhC channelizers that display these unique properties by allowing the control of the wavelength selective dropping characteristics by engineering both the dispersion surface and the bandgap of the PhC. In addition, the authors present experimental results of a series of simple yet efficient spectral filters. In particular, if two PhC slabs are combined, they form a sensitive displacement-tunable structure that can be utilized in designing functional tunable devices, such as switches, filters, modulators, and sensors.
