TD-BPM simulation exhibits high modulation efficiency of 0.61 dB/µm in graphene optical modulators based on the semiconductor-metal transition. Evaluation of graphene chemical potential in graphene-gate-metal MOS capacitors demonstrates feasibility of device principle for 1.55-µm wavelength.
We propose a dynamic compensation scheme of counter-propagating effect using PM-NOLM, and demonstrate a truly dynamic 8-period input/output optical transfer function, usable for 5-bit quantizing and encoding, a crucial number for the front-end of DSP. We investigate the effective resolution with the nonlinear error and the limitation of sampling rate, and numerical simulation will show the feasibility...
We present all-optical analog-to-digital conversion using optical time-interleaving and demonstrate dynamic 8-period input/output optical transfer function of PM-NOLM with dynamic counter-propagating effect compensation, usable for 5-bit quantizing and encoding, a crucial number for the front-end of DSP.
We demonstrate 4-bit analog-to-digital conversion at a sampling rate of 160 GSamples/s using 16-fold optical time-interleaving, and discuss how it is capable of Tera-Sample/s, 5-bit operations.
