We demonstrate a new way to design ultra-compact microwave channelizers by the combination of different types of lattices and properties of photonic crystals (PhCs). We also present and experimentally validate sensitive displacement tunable filters based on the guideded resonance of PhCs. PhCs offer the opportunity to construct ultra-small integrated circuits to overcome the limitations of integrated electric circuits. In this talk, we 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, we 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.
