In this paper we report an experimental investigation on the observation of surface plasmon resonance at the metal- dielectric interface of silver coated tapered light guiding glass rods of different dimensions. Chemical deposition technique has been used for metallic deposition of silver on the Tapered glass rod. Angular interrogation in Kretschmann- like configuration of this non-planar (cylindrical) structure is used to locate the resonance dip in the reflectance mea- surement. Fabrication simplicity, in addition to the inherent advantage of using different types of tapered structures, makes this study important in the development of nanoplasmonics. The experimental study is accompanied by some interesting results.
