Abstract
A silicon photonics based single wavelength 100 Gbit/s PAM4 DWDM transceiver in a pluggable form factor having a transmitter, said transmitter having: a DWDM laser source; a fiber array pigtail having a polarization maintaining fiber and an output single mode fiber; a silicon photonics modulator chip configured to optically connect to the DWDM laser source through the usage of the polarization maintaining fiber, a modulator driver chip connected to the silicon photonics modulator chip and an LC receptacle configured to optically connect to the silicon photonics modulator chip through the usage of the output single mode fiber. The disclosed transmitter may be further comprised of a reference loop within the silicon photonics modulator chip to allow for the utilization of a passive alignment approach for optically connected elements. The disclosed transceiver may be configured for use with C-band DWDM applications for utilization in applicable technologies, including 5G telecommunications.
