In this Letter,an effective method using a mode selective coupler(MSC),which is composed of a three-core fiber is presented to generate optical vortices(OVs).Th
The common and traditional method for optical dispersion compensation is concatenating the transmitting optical fiber by a compensating optical fiber having a h
Quantum dots are finding increasing commercial success in LED applications.While they have been used for several years in remote off-chip architectures for disp
To design a compact erbium-doped fiber laser, a high-concentration erbium-doped fiber(EDF) is needed. However, increasing the erbium ion(Er~(3+)) concentration
