Abstract

The group-delay characteristics of the light transmitting in a coupled defect waveguide (CDW) in a one-dimensional (1D) photonic crystal were experimentally investigated. Because of its simplicity, a 1D structure is suitable for scientific research as well as device application. The transmission spectrum agrees well with the calculated result by a characteristic matrix method. Group-delay measurement using the phase-shift method revealed the characteristic dispersion features and small group velocity of the CDW. This experimental investigation suggests that such unique features of the CDW promise the possibility of various applications such as a dispersion compensator.
