Abstract

In this paper, it is shown that the use of real trigonometric transforms can advantageously replace the Fourier transform in optical communication systems, for both all-optical and electronic signal processing. All-optical discrete Hartley transform (DHT) and discrete Cosine transform (DCT) architectures for high-speed optical signal processing, filtering and data compression are compared to fiber Fourier processing. A trigonometric transform-based OFDM transmission system is also proposed, where the modulation/demodulation is performed by using the FHT algorithm. The simplified scheme and the real processing make it suitable for optical systems.
