J. Debeau et al., WAVELENGTH TUNABLE PULSE GENERATION AT 10GHZ BY STRONG FILTERED FEEDBACK USING A GAIN-SWITCHED FABRY-PEROT LASER, Electronics Letters, 30(1), 1994, pp. 74-75
A source of near transform limited pulses (Delta t Delta f similar or
equal to 0.38) with pulse widths around 15ps, at a repetition rate of
10GHz, is realised using strong filtered self-injection of a gain swit
ched Fabry-Perot laser; this is achieved using a fibre loop feedback s
etup. The output is tunable over 11nm using the tunable filter in the
fibre loop.
