The architecture of the silicon photonic MEMS switch with gap-adjustable directional couplers. Light is coupled to the chip using the grating couplers. There are two pairs of the directional couplers and one comb-drive actuator per unit cell. The light paths on the chip are controlled by changing the gap spacing of each directional coupler.
