Slow-light dispersion in coupled periodic waveguides

Sukhorukov, Andrey A.; Lavrinenko, Andrei V.; Chigrin, Dmitry N.; Pelinovsky, Dmitry E.; Kivshar, Yuri S.


Periodic waveguides bring a new twist to the typical waveguiding problems of the intermediate case between photonic crystal waveguides and photonic wires or ridge waveguides. We develop an asymptotic theory applicable for a broad class of coupled periodic waveguide structures and use the analytical expressions to identify the generic types of dispersion in the vicinity of a photonic band edge, where the group velocity of light is reduced. We show that the dispersion can be controlled by the...[Show more]
