An efficient and stable laser action from a double-clad erbium/ytterbium-doped fiber (EYDF) is demonstrated using a fiber Bragg grating at room temperature. The fiber laser operates at wavelength of 1552.3 nm with a slope efficiency of 38% when pumpe

Strong optical and electrical interactions can occur between optoelectronic devices when the element-size and inter-element spacing are significantly reduced. In this paper, we study these interactions in the closely packed, positive index-guided sub

We theoretically propose an air-core erbium doped fiber amplifier capable of providing relatively uniform gain for 12 orbital angular momentum (OAM) modes (vertical bar L vertical bar = 5, 6 and 7, where vertical bar L vertical bar is the OAM mode or

We investigate control of the Q-switch rise time as a means to eliminate the undesirable formation of multipeak structure within actively Q-switched fiber lasers. Our experiments show that the development of pulse substructure is solely due to gain d

We experimentally demonstrate a few-mode erbium doped fiber amplifier (FM-EDFA) supporting 6 spatial modes with a cladding pumped architecture. Average modal gains are measured to be >20dB between 1534nm-1565nm with a differential modal gain of simil

We report a record multi-watt level and up to 45% efficient all-fiber frequency doubling in periodically poled silica fibers. Modulation instability is identified as the primary factor preventing further growth of the second-harmonic power.
