Abstract

Time-division demultiplexing is a key function for the development of high-bit-rate optical communication systems. An essential ingredient of a demultiplexer (DEMUX) is timing extraction (clock recovery). To control the DEMUX a signal synchronized to the clock-phase of the original data signal has to be generated. This can be achieved by optoelectronic means and by optical methods.^2-6 Considering optical methods only, the method of "injection locking" using self-pulsating^1-2 or mode-locked lasers^3-5 is simple compared to optical phase- locked loops.⁶ However, based on "injection locking" there are very few system experiments with bit-error-rate measurements.¹
