Experimental study on the properties of a four-stage optical time-division multiplexer in 16×10 Gb/s optical signal generation system

One time division multiplexer based on half-reflective coating lens as beam splitter/combiner and fiber length to control relative time delay between two channels was demonstrated and experimentally studied in detail. This time-division multiplexer is a serial structure with four stages, and a pulse stream with sixteen times repetition rate can be achieved with the multiplexers. Its characteristics including polarization properties were experimentally studied in 16×10 Gb/s optical signal generation system.
