Purcell effect in complex photonic structures based on optical Fibonacci lattices

The modification of probability of spontaneous emission for a dipole emitter that placed in Fibonacci lattice-based palindrome structures was examined. Localization properties of eigenstates, that appears in photonic band gaps of palindrome structure was investigated. It was shown, that for a dipole placed in centre of palindrome structure an increase in the spontaneous emission rate will be observed and, in addition, calculated value of Purcell factor is significantly greater than for critical localized states of usual Fibonacci lattices, and close to microcavity eigenmode case.
