Abstract

The promise of higher data-rate telecommunications links has focussed research efforts into all-optical signal processing schemes. Many of these have targeted digital operations using devices such as Semiconductor Optical Amplifiers (SOAs)[1] and micro-ring lasers[2]. Although all-optical digital processing will allow 3R (reamplification, reshaping and retiming) and logic operations, ultra-high-bit-rate communications, ultra-fast computing and data processing also require the capability to deal with analogue optical signals.
