, 16QAM = 4 bits/symbol, 64QAM = 6 bits/symbol), boosting capacity but requiring higher OSNR and more complex DSP. 16QAM is common in metro and regional coherent links where reach requirements are moderate and spectral efficiency is. silicon-based inphase/quadrature (IQ) modulators at symbol rates of up to 100 GBd. Our devices exploit the advantages of silicon-organic hybrid (SOH) integration, which combines silicon-on-insulator waveguides with highly efficient organic electro-optic (EO) c adding materials to enable small drive. In long-haul WDM (wavelength division multiplexing) optical communication systems utilizing the DP-16QAM modulation scheme, traditional methods for removing chaos have exhibited poor performance, resulting in a high bit error rate of 10−2 10 2 between the original signal and the removed chaos.
