Tamm states and nonlinear surface modes in photonic crystals

From the beginning of the 20th century, researchers have been interested in surface electromagnetic waves guided by planar interfaces of dissimilar mediums. Much initial research on surface-plasmon waves and surface-plasmonpolariton waves stemmed from theoretical curiosity, but the development of new experimental techniques propelled commercial exploitation for optical sensors of chemical and biological species. Additional surface waves called Dyakonov waves, Tamm waves, and Dyakonov-Tamm waves have emerged during the last 25 years. Experimental observation of Dyakonov waves was reported only in 2009, but the rapid development of experimental apparatus during the 1990s suggests that theoretical predictions will soon be evaluated experimentally, leading to further development of optical detection systems and optical circuitry.

“…In optics, it was found that electromagnetic surface modes, which are similar to the electronic Tamm states, can exist at the interface separating periodic and homogeneous linear dielectric optical media [4], in contrast to the interfaces between homogeneous dielectrics, where a prohibitively high nonlinearity is required for the existence of surface waves [5,6]. Optical analogs of Tamm and Shockley surface states have also been studied extensively in different types of photonic crystal structures [7][8][9][10][11][12][13][14].…”

We report on the experimental observation of novel defect-free surface modes predicted theoretically for modulated photonic lattices [I. L. Garanovich et al., Phys. Rev. Lett. 100, 203904 (2008)10.1103/PhysRevLett.100.203904]. We generate the linear surface modes in truncated arrays of periodically curved optical waveguides created in fused silica by a laser direct-writing technique. Our results demonstrate that the degree of surface wave localization can be controlled by selecting the waveguide bending amplitude.
