Ultra-fast quantum-well saturable absorber devices and their application to all-optical regeneration of telecommunication optical signals |
Abstract | ||
|---|---|---|
We review recent advances in the investigation of vertical cavity saturable absorber devices and their use for the all-optical
regeneration of telecommunication signals in ultra-long-haul transmission systems. Such devices are polarization-insensitive
and operate as fully passive nonlinear optical elements. Two approaches for obtaining fast recovery absorber materials are
described, relying upon ion irradiation or upon iron doping. The vertical micro-cavity devices are designed so as to optimize
the switching contrast and the operating power. Their functional behaviour as extinction ratio amplifiers has been characterized
and their optimal operating conditions have been determined. The potential application of these devices to all-optical regeneration
has been investigated through numerical simulations and fully demonstrated in several long-distance transmission loop experiments,
with results obtained at 10, 20 and 40 Gbit/s, showing significant improvements in system haul or operational margins. A four-channel
fibered module has also been fabricated, as a perspective towards the development of wavelength division multiplexing (WDM) saturable absorber modules. |
