Critique of CPO paper: Overlooking laser source complexity and ignoring bottlenecks

jwt0625 · x · 2026-08-22

The author criticizes the diagrams and configuration of a CPO (Co-Packaged Optics) paper, calling the QPSK modulator drawing unnecessarily complex. They question why MRM (Micro-ring Modulator) practitioners would imply using a supercontinuum source. Furthermore, the author notes the lack of discussion on external laser sources, reflecting the status quo of the CPO field being "choked by lasers while ignoring it."
