Abstract

We show that ultrahigh-Q wavelength-sized cavities can be reconfigurably formed by local refractive index tuning of photonic-crystal mode-gap waveguides. We have found that Q can be extraordinarily high (~5×109), which is much higher than that of structure-modulated mode-gap cavities. Furthermore, the required index modulation is extremely small (Δn/n~10-3), which enables dynamic cavity formation by fast optical nonlinearity. We numerically show that traveling photons in a waveguide can be pinned by fast local index tuning.

(a) Width-modulated line-defect mode-gap cavity in a 2D triangular-lattice air-hole photonic crystal slab. The red, green, and blue holes are shifted away from the line defect center by 9, 6, and 3 nm, respectively. (b) Index-modulated line-defect mode-gap cavity in the same photonic crystal slab. The refractive index of the red shadowed region is modulated as expressed by Eq. (1). (c) Theoretical band dispersion of the base W1 mode-gap waveguide (a row of missing holes in the Γ-K direction in a 2D triangular-lattice air-hole photonic crystal slab).

Optical field distribution (Hz, magnetic field perpendicular to the 2D plane) of index-modulated mode-gap cavities calculated by 3D FDTD method. Size parameters for calculations are described in the text. A red circle represents r=r 0 which describes the index modulation as in Eq. (1). r 0 is assumed to be 3a in all calculations except for Δn/n=0.06% where r 0=5a. The Q values are obtained with the 1244 grid condition for (a, b, c), and with the 1960 grid condition for (d, e).

Summarized performance of index-modulated cavities. Q and V eff as a function of Δn/n. Q 1 is obtained with the 1224 grids in the horizontal direction, and Q 2 is obtained with the 1960 grids. r 0 is 3a except the data point at Δn/n=0.06% and 0.04% where r 0=5a.

Snap shots of optical field distribution with index tuning. An optical pulse with the wavelength of 1641 nm is injected from the right end of a line defect waveguide. At t=1.025 ps, the refractive index of the red shadowed region is tuned by 0.8%. The temporal profile of the index tuning is shown in Fig. 5(a). The structural parameters are the same as in Fig. 2 except we employ the effective refractive index of n=2.8.

(b) No tuning case. (c) Tuned by Δn/n=0.8% at τ=0.1 ps at t=11.025 ps. (d) Tuned by Δn/n=1% at τ=0.05 ps at t=11.025 ps. (e) Tuned by Δn/n=1% at τ=0.5 ps at t=11.025 ps.
