Ultra-Low-Power Integrated Acousto-Optic Filter
The acousto-optic filter has gained increasing attention in wavelength-division multiplexed optical communication because it offers the unique and powerful capacity to extract many different wavelength channels (simultaneously and independently) from one optical fiber and divert all or part of each signal to a second fiber. This parallel-processing capability means that each wavelength in a fixed fiber network has an independently configurable matrix of interconnections.
