Slow light with high normalized delay-bandwidth product in low-dispersion photonic-crystal coupled-cavity waveguide

A two-dimensional (2D) triangular lattice photonic crystal coupled-cavity waveguide is designed and optimized. The transmission spectrum of the PC waveguide with TE polarization is calculated by using the finite-difference time-domain (FDTD) method, and the group velocity of c/131.18 at the wavelength is obtained. Through optimizing the parameters of photonic crystal waveguide, different resonance length are obtained by changing the number of the continous air holes. The smallest group velocity is obtained to be c/2209 in the coupled-cavity waveguide with 15 air holes. The mechanism of slow light in the coupled-cavity waveguide of photonic crystal is analyzed.

Crescent scatterers possess the properties of anisotropy and multiple degrees of freedom. With plane-wave expansion method (PWE), the slow light effect with high ngand low dispersion can be achieved by optimizing the structure parameters of photonic crystal waveguide with line defect, such as changing the radius of two circles and center distance. Slow light with low dispersion can be obtained by these methods, which implies that choosing suitable scatterers and adjusting their parameters can efficiently achieve slow light with high ng and low dispersion.
