In this manuscript, a dielectric nanoparticle-assisted excitation of optical Tamm mode (OTM) is proposed using a 1D-Photonic Crystal configuration. The structure comprises a bilayer photonic crystal structure having silicon nanoparticles placed at the top interface of the structure. The structural parameters and nanoparticle sizes are optimized to break the translational symmetry. The reflectance spectrum and field distribution map are analytically studied by the finite element method. The analytical results exhibit the excitation and confinement of OTM. The excited OTM modes show a strong dependency on the angle of incidence and the nanoparticle size. The obtained results exhibit that dielectric nanoparticles can be utilized as compact surface mode exciters and scatterers. This further facilitates the development of OTM devices for integrated photonic applications.
