Abstract

We present a technique based on the selective liquid infiltration of photonic crystal (PhC) waveguides to produce very small dispersion slow light over a substantial bandwidth. We numerically demonstrate that this approach allows one to control the group velocity (from c/20 to c/110) from a single PhC waveguide design, simply by choosing the index of the liquid to infiltrate. In addition, we show that this method is tolerant to deviations in the PhC parameters such as the hole size, which relaxes the constraint on the PhC fabrication accuracy as compared to previous structural-based methods for slow light dispersion engineering.

(a–b) TE-polarization band structures of a conventional W09 PhC waveguide (a) and a W09 that has its first two rows infiltrated with a liquid having a refractive index of 1.85 (b). On the insets, the respective PhC waveguide geometries (with hole radii r/a =0.3) are shown. (c–d) Associated group index (ng, green) and GVD (β2 blue) of the fundamental W09 mode in (a–b).

Fig. 2.

Even fundamental mode dispersion (bandstructure (a) and group index (b)) of the infiltrated W09 (with r/a =0.3) for various fluid refractive indices between 1.75 and 1.95. Only the first two rows are infiltrated.

Fig. 3.
Fig. 3.

Maps of the group index–bandwidth product that is achieved for the infiltrated W09 for various liquid refractive indices and hole radii. The bandwidth is calculated by considering the group index constant within ± 5% (a) and ± 1% (b). The superimposed solid lines curves correspond to constant values of the group index.

Group index of the even fundamental mode of the infiltrated W09 PhC with (a) r/a=0.31, and nf=1.8 (b) r/a=0.32, and nf=1.8 (c) r/a=0.33, and nf=1.75 (d) r/a=0.34, and nf=1.7. These operating points are highlighted with white dots on Fig. 3.

(a) Schematic of the waveguide with ac=480nm and a=420nm (b) Transmission spectra obtained through FDTD simulation for a 28 period infiltrated W09 PhC waveguide surrounded by two ridge waveguides (green) and two coupler sections and ridge waveguides (blue). The group index dispersion calculated through PWM (red) and inferred from the FDTD calculations (blue circles) is also plotted.
