1. An apparatus to facilitate optical signal transmission, the apparatus comprising:
a polarization beam converter (PBC), the PBC on a first chiplet;
a first optical input to receive a first light signal from a first optical transmitter, the first optical input optically coupled with the PBC;
a second optical input to receive a second light signal from a second optical transmitter, the second optical input optically coupled with the PBC, wherein a polarization converter is disposed between the second optical input and the PBC to convert the second light signal into a second light signal with altered polarization, wherein the first optical transmitter and the second optical transmitter are on a second chiplet, the second chiplet separate and distinct from the first chiplet; and
wherein the PBC is to combine the first light signal and the second light signal with altered polarization to transmit information carried on first signal and on the second signal on a same wavelength.
