Observation of photonic band-gap control in one-dimensional Bragg structures

Konoplev, I.V. and McGrane, P. and Phelps, A.D.R. and Cross, A.W. and Ronald, K. (2005) Observation of photonic band-gap control in one-dimensional Bragg structures. Applied Physics Letters, 87 (12). pp. 121104-1. ISSN 0003-6951

The results of experimental studies of scattering and interference of waves in one-dimensional photonic band-gap structures based on coaxial waveguides with corrugated inner and outer conductors are presented. Using numerical simulations and experimental measurements, the possibility to control the band-gap parameters is demonstrated. The experimental and theoretical results obtained are compared and discussed. It is shown that the variation of the relative phase of the one-dimensional corrugations with respect to each other results in a change of the band-gap parameters in accordance with simulated predictions.
