We report the experimental demonstration of a multiwavelength passively mode-locked fiber laser based on an all-fiber Lyot filter (AFLF). The is composed two 45°-titled gratings (45°-TFGs) and length polarization-maintaining (PMF). free spectrum range (FSR) 3-dB bandwidth are 7.5 nm 3.6 nm, respectively. generates 5-wavelength pulses, which have 7.49 channel spacing, 192.6 kHz fundamental repetition rate over 50 dB signal-to-noise ratio (SNR). As increasing pump power from 178 mW to 407 mW,...
High polarization extinction ratio (PER) in-fiber polarizers are essential in various fiber-based technologies. In this letter, we propose and demonstrate an dispersion compensated polarizer (DCP) based on integrated fiber gratings, which is fabricated by a UV-inscribed 45° tilted grating (TFG) chirped Bragg (CFBG) series. Such compact device could enhance the PER of TFG with nearly double value it potential to achieve ultra-high relatively short length simple fabrication. Meanwhile, DCP...
In this paper, we propose an optical scheme to generate four-mode cluster-type entangled coherent states (ECSs) in free traveling fields by using two single-photon sources, state beam splitters, photodetectors, cross-Kerr media, and phase shifters. And the success probability of preparation is calculated. At last discuss experimental feasibility such proposal.
There are two main drawbacks seen in the use of multi-gas detection method based on tuneable diode laser absorption spectroscopy (TDLAS). The first is that multiple lasers have traditionally been employed system, which means not only system cost, but also response time increased. second major issue existence a number kinds cross interference, and thus sensitivity accuracy existing multi-component gas approach has greatly restricted, this become technical bottleneck for practical multi...
We have proposed and experimentally demonstrated an ultrasensitive all-fiber angular displacement sensor based on in-fiber polarizing gratings half waveplate (IFHWP), in which the are 45°-tilted fiber (45°-TFGs) IFHWP is constructed by bending-induced birefringence single mode (SMF). Compared with existing sensors, structure of our more desirable to bring prominent advantages structure, low transmission loss high sensitivity. The experimental results show that has a sensitivity resolution up...
We demonstrated Erbium-doped mode-locked fiber lasers by using a chirped Bragg grating (CFBG) as dispersion managing element. Both conventional soliton and M-shape pulses were achieved when the laser operates in large anomalous normal regime controlling direction of CFBG, respectively.
