The transmission and processing of signals carried by optical beams rather than by
electrical currents or radio waves has been a topic of great interest ever since the early …

One hotspot of integrated optics is how to realize a highly integrated and high-gain on-chip
amplification system in a thin film of lithium niobate on insulator (TFLNOI). Here, a low …

High-concentration Er/sup 3+//Yb/sup 3+/co-doped silica waveguide amplifiers are
