Abstract

The optical signal regenerator has become the subject of great attention because of its potential for greatly extending the maximum transmission distance for high-bit-rate optical time-division-multiplexing (OTDM) systems. In particular, interferometric optical and gates^1-4 are attractive for the regenerator because they can compress the variations in both intensity and timing phases. It is important to clarify the regenerator characteristics quantitatively, and to our knowledge this has not been done to date. In this paper we quantitatively study the feasibility of the interferometric regenerator by measuring the system bit-error-rate (BER) performance at 10 Gbit/s for what we believe to be the first time.
