Abstract
ABSTRACT We demonstrate 8 x 2.5 Gb/s OThM data demultiplexing using a semiconductor laser amplifier in a loop mirror (SLALOM). The switching window of the SLALOM was set to 30 ps. Both all and 2 -1 pseudorandom codes were used for comparison. By an average control power of 1 .6 mW the output signal extinction ratio was estimated to be 8 dB.Keyword: optical time division multiplexing, semiconductor optical amplifier, semiconductor laser amplifier in a loop mirrorThe semiconductor laser amplifier in a ioop mirror (SLALOM) has attracted much attention for optical time divisionmultiplexing (OThM) in wavelength conversion'1, optical clock extraction21, data demultiplexingt3'41 and other optical signalprocesses5'61. Compared to the fiber based nonlinear optical loop mirror (NOLM) SLALOM possesses following excellentproperties: compact size, mtegratable with other optical waveguide devices, and much higher optical nonlinear coefficient inthe active region of the semiconductor optical amplifier (SOA) which is high desirable in optical switching applications.Whereas the long carrier lifetime ( 500 ps) ofthe semiconductor material had hampered it in high speed application for a longtime. This drawback has been bypassed by using either period intense control pulses to setup a constant saturation statefl, or a
