Silica optical fiber derived from yttrium-aluminum-garnet (YAG) crystals is an excellent high-gain fiber due to their high rare earth ions doping concentration. It offers a new opportunity of addre…
To satisfy the increasing requirements for high-quality cavity mirrors for semiconductor lasers, the influence of the anisotropic stress field generated by scratching GaAs on the quality of cleavag…
An opticalfiber vector magnetometer based on a thin-cladding polarization-maintaining fiber (TPMF) long-period fiber grating (LPFG) and magnetic fluid (MF) is proposed and experimentally demonstrat…
The key idea of this work is to treat the symbol- pattern-dependent inter-symbol-interference (ISI) that is avoided in conventional single-symbol modulation systems as useful symbol correlation, in…
Two kinds of Yb-doped fibers were fabricated, namely, Yb: YAG crystal-derived silica fibers (YCDSFs) with a gain coefficient of 6.0 dB/cm, and Bi/Er/Yb co-doped silica fibers having a Yb concentrat…
