MULTIWAVELENGTH 10-GHZ PICOSECOND PULSE GENERATION FROM A SINGLE-STRIPE SEMICONDUCTOR DIODE-LASER

A single-stripe GaAs-AlGaAs semiconductor optical amplifier (SOA) has been used to generate four tunable wavelength-division multiplexed (WD M) channels simultaneously, each transmitting 12-ps pulses at 2.5 GHz, for an aggregate pulse rate of 10 GHz, Wavelength tuning over 18 mn h as been demonstrated with channel spacing ranging from 0.8 to 2.1 nm, A potential spectral correlation across the multiwavelength spectrum h as been studied in both experiment and simulation methods, These resul ts show the potential for utilizing single stripe laser diodes as mult iwavelength sources in WDM-TDM network.
