In this paper, we show experimentally for the first time a 2 GSamples/s optically sampled analog-to-digital converter based on dual-output modulation and balanced photodetection scheme. Linearization in the form of arcsine operation is also described to illustrate the considerations of the proposed scheme. Finally, arcsine operation is digitally implemented on the output of the electronic ADC and...
In this paper, we show analytically for the first time that the complementary phase properties of a polarization modulator can be utilized to cancel the dispersion-induced second-order distortions in a Time-Stretched Analog-to-Digital Converter (TSADC). Using differential operation and digital post- processing in the form of arcsine operation, this enables the suppression of system nonlinearities-induced...
In this paper, we show analytically and experimentally that a polarization modulator which supports TE and TM modes of opposite phase modulation indexes can be utilized to reject dispersion-induced even-order distortions in a photonic Time-Stretched Analog-to-Digital Converter (TS-ADC). The output of the polarization modulator propagates through a single dispersive channel. This makes the present...
