We have analyzed the characteristics of three types of gap plasmon waveguides having wavelength selective functions: one is structured by a Fabry-Perot resonator with reflectors, one is structured by a slot resonator and the other is the waveguide with a single or two stubs. We have presented the numerical results of the transmittance spectra for these structures calculated by using the finite-difference time-domain method. The numerical results have clearly indicated that all structures of a sub-micron size work properly as wavelength selective devices. The advantage of a stub type of waveguide is on easiness in fabricating, while that for a Fabry-Perot type of waveguide is to lead to making the size decrease considerably and relatively high Q-factor.
