The Design Of Linearly Polarized Dual-Wavelength Fiber Laser Which Used In Wdm-Rof-Pon

In this paper, we design a linearly polarized dual-wavelength fiber laser used in WDM-ROF-PON, which can achieve wire-line and wireless access synchronously. The all-fiber linearly polarized dual-wavelength fiber laser uses a PM chirped FBG and a PM FBG as the resonant cavity mirrors. Due to the PHB, a steady dual-wavelength laser can be realized. With polarization multiplexing, the dual-wavelength fiber laser is the union light source of WDM-PON. With the CSRZ-DPSK modulation, the wireless access system can save RF resource in ONU and the frequency of radio carrier can be controlled by OLT. The networking has the credible transmission property, including wireless access and fiber transmission. (C) 2013 Elsevier GmbH. All rights reserved.
