This paper presents the unique behavior of thulium doped fiber amplifiers (TDFAs) under circumstantial changes in the multi-wavelength photonic networking systems, namely in the span loss, the channel count, and the environmental temperature. Unlike

Many Bi x Pb y Sr 2 Cu 3 O z glasses (1.6 ≦ x 4.0, 0.2 ≦ y ≦ 1.6) were prepared by using the conventional melt-quenching method and the glass fiber drawing ability was examined. The glass transition (365–390°C) and crystallization peak (425

A novel planar lightwave circuit device called variable attenuation slope compensator (VASC) is proposed for active gain slope control in EDFAs. Its attenuation slope is electrically controllable with the average attenuation unchanged.

The Ag‐coated superconducting Bi2 Sr2 CaCu2 Ox glass‐ceramic fibers were successfully prepared. The glass fibers with a length of 50 cm, a width of 100–200 μm, and a thickness of about 20 μm were first drawn from glass plates with a thickness
