Abstract

Although ultrashort optical pulses are used for the time-domain study of transmission of pulses through dispersive media, interferometric measurements using white light with an ultrashort correlation time can very often be much more powerful and useful [1,2]. Here, we present an application of Fourier-transform interferometry to the study of photonic band structure in a one-dimensional quasiperiodic structure. Photonic band formation in periodical dielectric structures and localization of light in random structures have been a subject of great interest in recent years [3]. Studies on photonic quasiperiodical structures will extend this new area of research furthermore. Our sample of one-dimensional quasiperiodic system was a photonic Fibonacci lattice, which was proposed by Kohmoto et al. [4]. Fractal behavior of wave functions and the energy spectrum in it has been theoretically predicted.
