Abstract :
A novel cell multiplexer for generating time-multiplexed ultrafast optical cells for the photonic ATM cell switch is presented. This multiplexer mainly consists of speed convertors which can compress the intervals of ultrashort optical pulses according to the binary multiplicative principle and make ultrafast optical cells of any length with minimal hardware. Generation of a four-bit 40 Gbit/s optical cell by the speed convertor is demonstrated.
