Abstract

In a practical photonic switching system using integrated optic devices, crosstalk and control are more of a problem than optical loss. In this paper, performances of photonic gate-type matrix switch¹ and a time slot interchanger² using cascaded-structured integrated optic modulators and switches are analyzed. Both have shown improved signal-to-crosstalk ratios (SXR) and the possibility of using a common control voltage without tuning for the switching components. We also compare these two photonic systems with those using conventional components by considering other performance factors such as optical insertion loss, device count, switch capability, and possible switch size, etc.
