New advances on optical components needed for FDM optical networks
TL;DR: In this article, two critical components, needed for optical networks based on frequency division multiplexing (FDM) and frequency reuse technologies, are presented: a fast tunable laser, yielding 24 discrete frequencies regularly spaced by 40 GHz around 1.53 mu m, and a broadband wavelength shifter capable of switching multigigabit data between optical frequencies in the 1.5- mu m region.

Cascadability and fanout of semiconductor optical amplifier wavelength shifter
Jay M. Wiesenfeld,Bernard Glance +1 more
TL;DR: In this paper, two cascaded, broadband wavelength shifters operate using gain saturation in semiconductor optical amplifiers to copy data from a modulated pump signal, in which the intensity of the marks is sufficient to significantly compress the gain of the amplifier, to a CW probe signal.

Optical Bistability in a Semiconductor Laser Amplifier
TL;DR: Optical bistability has been observed in a semiconductor laser operating as an amplifier as mentioned in this paper, which arises from the refractive index change due to a decrease in the active region carrier density accompanied by optical amplification.
