Multi Wavelength

A ring cavity multiwavelength Brillouin erbium-doped optical fiber laser （EDFL）based on the stimulated brillouin scattering effects and linear gain mechanism of erbium-doped fiber was demonstrated, in which single mode fiber was used as Brillouin gain medium and the Stokes signal was amplified by using the erbium-doped fiber amplifier, so that the laser can produce a stable multi-wavelength output at room temperature. Through the study and analysis of the position of the circular and coupler and the access mode of the coupler, we found that they both had influence on the output of the brillouin-erbium fiber laser. Then we have done some experiments at the Brillouin pump power of 14 dBm and the 980 nm pump power of 23 dBm, and single mode fiber length of 10km. The results showed that the access mode of the coupler affects the output of the brillouin-erbium fiber laser obviously. The detailed test results and the corresponding explanation were given.

Birefringence Effect

Abstract A switchable and tunable erbium-doped fiber laser with a linear cavity based on fiber Bragg gratings embedded in Sagnac rings is proposed and experimentally verified. Due to the stress birefringence effect and the polarized hole burning effect, which are introduced into the single-mode fiber in the polarization controllers (PCs) by the PCs, the designed laser can achieve seven kinds of laser-states output including three kinds of single-wavelength laser states, three kinds of dual-wavelength laser states and one kind of triple-wavelength laser state. The optical signal-to-noise ratios of the output wavelengths are all higher than 52 dB, and the wavelength shifts are all less than 0.04 nm. Furthermore, the temperature tuning of the wavelength range is also researched, which is about 1.2 nm. Due to advantages, such as low cost, simple structure, easy switching and multiple laser states, the designed laser has great application potential in laser radar, optical fiber sensing and so on.

Code Division Multiple

In this paper, the performance of a spectral amplitude coding-optical code division multiple access (SAC-OCDMA) system is investigated utilizing a single photodiode (SPD) detection technique. The proposed system uses enhanced double weight (EDW) codes as signature codes with three simultaneous users to overcome both phase-induced intensity noise (PIIN) and multiple access interference (MAI). In addition, a dispersion compensating fiber (DCF) is used in order to decrease the group velocity dispersion (GVD) caused in the single mode fiber. An erbium-doped fiber amplifier (EDFA) is used to overcome the attenuation. The use of both DCF and EDFA leads to an appreciable enhancement in the system performance. The system performance is evaluated through its bit error rate (BER), Q-factor, and received power. A comparison between the EDW codes and modified double weight (MDW) codes on the SAC-OCDMA system is demonstrated. Simulation is carried out through Optisystem ver. 7. The simulation results show that: (a) using an avalanche photodiode (APD) over PIN photodiode allows data transmission over longer distances; (b) the use of DCF improves the system BER;(c) using MDW codes gives better BER than using EDW codes.
