20Gb/s seamless 2×2 MIMO transmission of W-Band millimeter-wave signals over a 30-km modal-dispersion-compensated mode-division multiplexed link and a 2.5-m wireless path, is demonstrated for enhancing the transmission capacity in radio-over-fiber systems.
Few-mode multicore fiber (FM-MCF) has the potential to improve the transmission capacity of a fiber drastically. Challenges in designing FM-MCF and characteristics of our fabricated FM-MCF for highly dense space-division multiplexing are reviewed.
We have demonstrated an output power of 5.6 W at 1180 nm in linearly-polarized fiber laser using a low-loss ytterbium-doped polarization maintaining solid photonic bandgap fiber. A slope efficiency of 31 % has been achieved.
A linearly-polarized fiber laser operating at 1180 nm was demonstrated using a low-loss ytterbium-doped polarization maintaining solid photonic bandgap fiber. A slope efficiency of 30 % was achieved.
A low loss ytterbium-doped polarization maintaining solid photonic bandgap fiber (SPBGF) is fabricated using a new fabrication method. A high efficient fiber laser operated at the low-gain wavelengths is prospected by the fiber.
