Abstract [en]

Present days, plasmonics/metal optics and photonic crystal are two promising ultra photonics integration technology available to match the dimension of optical devices with decreasing electrical device size. As, fabrication and design/optimization are two challenges inpractical implementation of these technologies, plasmonics or metal based optics has extraedge in the area of design/optimization because of the applicability of quasi-static approximation which lead to use of circuit theory in plasmonic devices. Moreover, large number ofwell studied metal structure are available from microwave and millimetre wave applications and these can be scaled down to be used in optical frequency regime. From this thought, abandpass ltering mechanism concept called 'end-coupled halfwave resonator' is borrowed from microwave engineering and investigated in optical frequency regime with scaled downsize of nm order. The result shows both lumped-element model and distributed-elementmodel can be utilized for the design using approaches used in microwave engineering. Finally, some modications and applications of the structure are proposed to utilize the lterin optical frequency regime.
