چکیده
This paper outlines an approach to optical feedforward linearisation technique to reduce nonlinear distortion generated by a directly modulated semiconductor laser diode for Wireless Local Area Network (WLAN) operating in the Industrial Scientific -Medical (ISM) band 2.4 GHz (IEEE802.11b) for Radio over Fibre (RoF). Various linearization techniques are reviewed. Results with feedforward linearis ation have shown over 10 dB reduction in Intermodulation Distortion IMD in frequency range of 2.2 GHz – 2.7 GHz.

متن کاملImproved Intrinsic Dynamic Distortions in Directly Modulated Semiconductor Lasers by Optical Injection Locking
The effects of optical injection locking on the nonlinear distortions of directly modulated semiconductor distributed feedback (DFB) lasers are investigated experimentally. The second harmonic distortion (SHD) and third harmonic distortion (THD), as well as the third-order intermodulation distortion (IMD3), are measured as functions of modulation frequency for both the free-running and injectio...
