Abstract :
Summary form only given. We have experimentally demonstrated that optical injection locking is very effective in suppressing the second harmonic distortion in directly modulated semiconductor lasers. More than 15 dB reduction in second harmonic distortion has been observed from 2 to 4 GHz. This technique is very useful for high performance sub-carrier multiplexed fiber optic systems with carrier frequencies of several GHz
