Abstract

We have successfully designed and fabricated the silicon photonics integrated circuit for a 1.6 Tbps co-packaged optics, consisting of low-loss crossings, wavelength multiplexers, and optical modulators. The optical insertion losses of siliconnitride crossing structure and wavelength multiplexers were less than 0.2 dB and 3.0 dB, respectively. Those passive components enabled low-loss optical transmitter circuits for four-parallel CWDM4 application.
