چکیده انگلیسی
A method for a 1550Â nm vertical cavity surface emitting laser (VCSEL)-based 10Â Gb/s optical non-return to zero (NRZ) signal transmission over 20Â km single mode fiber (SMF) using reflective semiconductor optical laser amplifier (RSOA) gain saturation is presented. The optical signal distortion of 10Â Gb/s optical NRZ signals caused by the inherent frequency chirp of the VCSEL and the chromatic dispersion of SMF were investigated through numerical simulations and experiments. For 20Â km transmission over SMF, VCSEL-based 10Â Gb/s optical NRZ signals were severely distorted and '1' bit signals had different amplitudes with respect to their bit patterns. The gain saturation of RSOA can equalize the different amplitudes of '1' bit signals and can mitigate the optical pulse distortion after 20Â km transmission over SMF. The experimental results showed that VCSEL-based 10Â Gb/s optical NRZ signals can achieve a bit error rate (BER) of 10-9 with a 2.4Â dB dispersion penalty for 20Â km transmission of SMF with RSOA gain saturation.
