Line Coding for Downlink DML Modulation in λ λ-Shared, RSOA-based Asymmetric Bidirectional WDM PONs
Line Coding Downlink DML Modulation λ λ-Shared RSOA-based Asymmetric Bidirectional WDM PONs
2015/5/20
We experimentally investigate the use of various DC-balanced line codes for downlink modulation in single-fiber, wavelength-shared WDM-PON systems which employ 10-Gbps directly modulated lasers and 2....
Implant Enhanced Dual Intracavity Polarization Switching Asymmetric Current Injected VCSEL
Implant Enhanced Dual ntracavity Polarization Switching Asymmetric Current VCSEL
2015/5/15
Output polarization is controlled by injecting current along crystalline directions. VCSELs with record-low threshold current of 0.19 mA and extinction ratio >21dB from fit is achieved. Polarization s...
