چکیده
We present a post-distortion linearization technique for semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) photonic sampler. The sampling source is an active mode-locked laser producing 12.6 ps-width pulses with repetition frequency of 10 GHz. mathematical model the presented and then evaluated quasi-static regime, i.e. continuous-wave signals, dynamic sinusoidal signals. A significant improvement in terms total harmonic distortion (THD) equal to 23.4 dB observed modulation index 80% matching highest THD regime.

Adaptive optical post distortion linearization.
A technique to suppress optical nonlinearities is demonstrated using adaptive optical domain post distortion. The concept, rooted in electrical domain linearization, mitigates optical nonlinearities by generating sidebands that are equal but opposite in phase from the unwanted components. We model and experimentally demonstrate >20 dB extinction in four wave mixing by an adaptive phase controll...
متن کاملAdaptive Post-distortion for Photodetector Linearization
Nonlinearities due to photodetector saturation limit the maximum dynamic range achievable in short fiber optic links. We demonstrate an adaptive method for photodetector linearization using a monolithic CMOS polynomial generator. Improvements of 16 dB and 5.1 dB are achieved in the 2 and 3 order limited dynamic ranges, respectively.

متن کاملImproved Second Harmonic Linearization Technique for Multichannel Amplifiers with Enhancement Reducing in Intermodulation Distortion
A linearization technique for reducing third-order intermodulation distortion that uses the injection of the fundamental signal second harmonics together with the fundamental signals at the amplifier input has been improved in this paper. The procedure proposed introduces phase correction of the fundamental signals according to the differences in phase of the second harmonics. Linearization tec...
متن کاملA Novel Power Amplifier Linearization Technique based on Pre-distortion Principle and Wiener model
The new generation mobile communication systems are very sensitive to the nonlinearities in their transmitting paths. The power amplifier is a key component which generates the nonlinear distortions. Power amplifier linearization techniques are very important to reduce the distortion of the transmitted signal and the adjacent band interference of users. As its facility of implementation, adapti...
