240 Gb/s optical transmission based on an ultrafast silicon microring modulator
文献摘要：
An ultrafast microring modulator(MRM)is fabricated and presented with Vπ·L of 0.825 V·cm.A 240 Gb/s PAM-8 signal transmission over 2 km standard single-mode fiber(SSMF)is experimentally demonstrated.PN junction doping concentration is optimized,and the overall performance of the MRM is improved.Optical peak-ing is introduced to further extend the EO bandwidth from 52 to 110 GHz by detuning the input wavelength.A titanium nitride heater with 0.1 nm/mW tuning efficiency is implemented above the MRM to adjust the resonant wavelength.High bit rate modulations based on the high-performance and compact MRM are carried out.By adopting off-line signal processing in the transmitter and receiver side,120 Gb/s NRZ,220 Gb/s PAM-4,and 240 Gb/s PAM-8 are measured with the back-to-back bit error ratio(BER)of 5.5×10-4,1.5×10-2,and 1.4×10-2,respectively.A BER with different received optical power and 2 km SSMF transmission is also investigated.The BER for 220 Gb/s PAM-4 and 240 Gb/s PAM-8 after 2 km SSMF transmission is calculated to be 1.7×10-2 and 1.5×10-2,which meet with the threshold of soft-decision forward-error correction,respectively.
