Abstract
In this paper, we propose a novel 32 Ã 32 photonic bandgap (PBG) power switch based on silicon-on-insulator (SOI) substrate. The 32 Ã 32 PBG power switch merges the design concept of PBG structure and multimode interference (MMI) structure. With controlling the voltages of 256 blocks for changing the refractive index, we can demonstrate that the light propagation direction can be switched to the assigned output port as a 32 Ã 32 power switch. According to the simulations, the power switching control tables are searched and selected for successful switching. The size of our designed 32 Ã 32 PBG switch can be reduced to 252 Ã 6040 μm which is much smaller than the conventional opto-electronic switches.
