Abstract
We demonstrate an all-optical wavelength-division-multiplexing ring network immune to transients based on
individual optically gain clamped waveguide amplifiers. The ring network is compared to a similar point-to-point
configuration to quantify the effect of recirculating amplifier noise. In the results, we notice that the optical
stabilization is strong enough to overcome the effect of accumulated amplifier noise over the entire transmission
bandwidth, and no lasing or chaotic behavior occurs. In addition, due to the independent amplifier stabilization,
the network has shown to be robust even in the case of failure and restoration. We prove that the obtained results
are scalable with the amplifier number. All results are also applicable to fiber-based amplifiers.
