Photonic switching systems can generally be divided into three categories space-divisionSD121, TIME-DIVISIONTD3, and wavelength-divisionWD4. However, for important goals, such as transmission and management of large amounts of video information, a combined system must be used for high degrees of multiplexity. This paper proposes a combined photonic TD and WD switching network for a photonic switching system. This paper compares the number of optical devices required for this proposed structure with conventional structures. And, finally, This paper shows how the proposed structure can further reduce the total number of optical devices required.
