R. Hui et al., Generation of ultrahigh-speed tunable-rate optical pulses using strongly gain-coupled dual-wavelength DFB laser diodes, IEEE PHOTON, 11(5), 1999, pp. 518-520
A novel and simple method to generate a variable-rate, ultrahigh-speed opti
cal pulse train is demonstrated using a dual-wavelength, strongly gain-coup
led distributed-feedback laser diode, The repetition rate of the optical pu
lse train is continuously tunable from 25 to 80 GHz and no high-speed elect
ronics are required in this method.
