Analytical investigation to achieve the highest phase difference between two orthogonal components of light in lithium niobate based electro-optic system
TL;DR: In this paper, a multi-passing technique is used to create a high degree of phase difference between those two orthogonal polarized components of light against the biasing signal, which enables more and more optical path length for the light.

Increase of Side Band Powers in Parallel Phase Modulation by Lithium Niobate–based Electro-optic Crystal
TL;DR: In this article, the authors proposed a new scheme where a single biasing electrical field is parallelly applied in two orthogonal directions at a time on a specific light signal, instead of one biasing signal on the light beam.

EDFA transient response to channel loss in WDM transmission system
TL;DR: In this article, the effects of channel loss on an erbium-doped fiber amplifier (EDFA) in an eight-channel WDM network were investigated, and the authors showed that for the loss of 1, 4, or 7 channels, the surviving channels suffer power transients which can be both large and relatively fast.
