IEEE Photonics Technology Letters 4
We report all-optical synchronized multiplication
by rational fractions of the modulation frequency of optical
signals in self-pulsing two-section semiconductor laser diodes.
The effect is based on the overlap of harmonics of the input
signal with harmonics of the self-pulsation. We illustrate this
new generic function with modelocked inputs rich in harmonics
were fractions of 1,2, and 3 / 2 are generated, and we identify a
number of applications for this effect.
