| Summary: | 碩士 === 國立臺灣師範大學 === 光電科技研究所 === 93 === In this thesis, we provide a simple but novel solution for WDM/PolSK fiber-optic communication system. We use a 1.3 μm SOA, 1×4 channel WDM MUX/DeMUX, 90:10 2×2 fiber couplers, and 50:50 1×2 fiber couplers to form a WDM symmetric resonator laser. By combining the resonator laser and phase modulators together, we can provide a well performance multi-level WDM/PolSK light source. Besides, we design a multi-channel Stokes receiver as the polarization-state measured WDM/PolSK receiver to track the changes of the SOPs of the WDM/PolSK lightwave. By using the multi-channel Stokes receiver, we can easily observe and analysis the changes of the SOPs. Moreover, we set up a WDM/PolSK fiber-optic transmission experiment with 1Gbps signal. In this experiment, we track the SOP variation by using the multi-channel Stokes receiver. Moreover, we compare the received signal with the initial signal to see the performance of our WDM/PolSK transmission system and check the practicalities of our homemade components in the WDM/PolSK fiber-optic communication system.
The proposed design of our WDM/PolSK fiber-optic transmission system can serve as another possibility for PolSK signaling for high spectral efficiency and low symbol-rate systems. We can validate this WDM/PolSK scheme as a potential solution for future high-speed modulation format.
