"achieves high data rates while mitigating channel density/ crosstalk by integrating hybrid wavelength-port multiplexing alongside complementary broadband lattice-filter multiplexers/ compact Vernier dual-microring demultiplexers... PAM4 signaling, FPGA-assisted adaptive wavelength-locking framework with closed-loop thermo-optic control actively compensating for thermal drift... resonator-based, with optical I/O integration necessary to support massively parallel AI computing clusters"
