Characteristics of DBR structures.

(a) Measured and simulated reflectance spectra of 12.5-pairs SiO2/Si3N4 DBR structures, where the background indicates the corresponding color. (b) Schematic of nano-photoelectrode with DBR structures for FDTD simulation. (c,d) show the simulated energy density distribution in nano-photoelectrode without/with DBR structures in the X-Z plane, respectively.
