FIG. 1.

(a) Cross-sectional schematic of the CDC. (b) Top-view schematic of the CDC with dimensions , , and . (c) Photonic band diagram of the composite structure along the propagation direction. The light cone for the cladding is located on the upper left portion; operating at as indicated by the dotted horizontal line, with (OFF) or 0.2633 (ON). The dark solid lines represent even symmetric modes about the axis at the center of the core. Dotted lines denote odd symmetric modes. (d) Top-view and cross-sectional optical mode profile for operation along the first photonic band. The optical mode, initially guided only in the layer (outside the CDC), is guided in the hybrid structure within the CDC as shown.

FIG. 2.

Predicted relationship between injected carriers and drive current along with the voltage characteristics of the CDC. Turn-on power is approximately 114 nW. Left inset shows the entire dopant and current relationship with voltage from 0 to 10 V. Right inset shows characteristics that 2D simulation (the case without PhCs) would have overestimated the power usage, especially during fast switching when the anode is driven higher.

Image of FIG. 3.
FIG. 3.

Simulated relative phase and dispersion shift of the CDC as a function of operating frequency in biased and unbiased settings.
