64 channel, 100GHz VMUX with low-power, fast attenuators in high index contrast PLC

Low-loss high-index-contrast designs enabling the monolithic integration of a 64 channel, 100 GHz VMUX in a compact die have been developed. The power consumption of the attenuators is reduced to 20 mW and the switching speed increased to 0.5 mS by electrical overdriving.
