Abstract
For the first time, we have experimentally demonstrated an all-silicon polarization-multiplexed IQ modulator targeting 800ZR pluggable transceivers for data-center interconnection. Using realistic DAC, ADC, DSP, and commercially available driver amplifiers, we can achieve an equivalent transmitter output power of -15.74 dBm and an rOSNR of 26.51 dB with oFEC. Furthermore, a superior performance showing a transmitter output power of -13.55 dBm and an rOSNR of 26.6 dB can be achieved by using a future co-packaged driver chip with peaking capability, which is experimentally emulated by an optical spectral shaper. In addition, an optical sub-assembly consisting of co-packaged a SiPho chip and a TIA chip is under sample building and testing. The demonstration paves a way for near-term available 800ZR pluggable transceivers based on silicon photonics.
