A 40 GB/S PAM4 Silicon Microring Resonator Modulator Transmitter in 65NM CMOS Conference Paper uri icon


  • © 2016 IEEE. A silicon photonic microring resonator modulator transmitter utilizes a segmented pulsed-cascode output stage for voltage level control to achieve PAM4 modulation on a single microring device. The 65nm CMOS transmitter achieves 40Gb/s operation at 3.04mW/Gb/s when driving depletion-mode microring modulators with 4.4Vppd swing.
