We report the observation of an ultra-narrow band plasmon induced transparency resonance which is realized in a large area hybrid plasmon-waveguide system consisting of a gold nanowire array embedded in a slab waveguide. Due to the destructive interference between optical modes supported by the hybrid system, an ultra-narrow plasmon induced transparency resonance with a bandwidth of 8 nm at the wavelength of 966 nm was obtained (i.e., similar to 1/120 of the peak wavelength at the incident angle of 60 degrees). The group velocity is estimated to be similar to 76, which is promising for miniaturized slow-light components. (C) 2011 American Institute of Physics. [doi:10.1063/1.3659309]
