Sqrl, from the website, Active” devices include lasers, photodetectors and modulators that are fabricated out of compound semiconductor materials. In POET’s case they are built from Indium Phosphide, a material that emits light when charged with an electric current. The POET Optical Interposer uses a version of active devices that are constructed to allow them to be “flip-chipped” onto the surface of the Interposer. Importantly, this design allows a wide variety of active devices available from many sources to be integrated onto the POET Optical Interposer platform. This feature provides maximum flexibility for device designers to use the POET Optical Interposer for a wide variety of applications.

I believe they are using InP modulators with PAM4 to achieve 400Gbs transceivers, if they were to partner with LWLG modulators I believe the combined effort transceiver would easily become defacto "tons the best" of the Industry and gain right about 100% of the market imo
