摘要

A stable and narrow wavelength spacing multiwavelength erbium-doped fiber laser is proposed and demonstrated. The laser can producesimultaneous dual-and triple-wavelength lasing oscillations with a narrow wavelength spacing of less than 0.1nm via using a singlefiber Bragg gratings written in polarization-maintaining (PM) fiber. By adjusting polarization controller, the wavelength spacing of dualwavelengthlasing oscillations can be tuned to as small as 0.032nm. The maximum amplitude variation for every lasing wavelength is lessthan 0.5 dB. The room-temperature operation principle is based on the polarization hole burning and deeply saturated effect in an ordinaryerbium-doped fiber ring laser (EDFRL). The laser has the advantages of simple all-fiber configuration, low cost, high stability andoperating at room temperature

摘要

Long period fiber gratings are fabricated in the cladding rods ofall-solid photonic bandgap fibers (PBGFs) by point-by-point side UVillumination. Resonant couplings from fundamental mode to guided andradiative supermodes (rod modes), and bandgap-like modes are identified.We obtained a detailed insight over the modal and dispersive properties ofthe PBGF through a series of theoretical and experimental investigations onthe spectral characteristics and the responses to temperature and high-indexliquid of the LPGs.

摘要

The temperature tuning properties of a liquid crystal (LC) photonic bandgap fiber's bandgap transmissionwas investigated in this study. Because of the special temperature responses of the LC's indices andits phase transition property, the bandgap transmission was found to have different temperature responsesat different temperature ranges below the LC's clearing point temperature. At temperatureslower or higher than the LC's clearing point, the bandgap transmissions are quite different, which permitsswitching with an extinction ratio as large as 45 dB. At temperatures around the LC's clearing point,the bandgap transmission was depressed.
