  • Abstract
    In this letter, an all-optical discrete Fourier transform (DFT) device based on multimode interference (MMI) couplers is proposed. The DFT device is composed of a discrete sine transform device and a discrete cosine transform device, both of which are based on MMI couplers. The main advantage of this DFT device is that it is composed of two compact MMI couplers, which greatly reduces the fabrication effort on planar lightwave circuits.
