InP light sources
Imec and CST Global announced they have successfully integrated InP distributed feedback (DFB) lasers from CST Global’s InP100 platform into imec’s integrated silicon photonics platform (iSiPP).

The InP lasers were ‘flip-chip’ integrated onto the SiPho circuits through a die-to-die bonding process, aligning efficiently and coupling over 5mW into the SiN waveguides on the SiPho chip.

“We are excited to work with CST Global to extend imec’s silicon photonics portfolio with hybrid integrated InP light sources. Our first passive laser assemblies have demonstrated excellent initial results. Throughout 2020, we will further optimize the precision and throughput of the laser assembly process; extend the functionality to include RSOA integration at 1310/1550nm wavelengths; and perform reliability qualification. We expect that the availability of these hybrid, integrated light sources will boost industrial uptake of SiPho devices in a variety of cost-sensitive markets. Early access through imec’s iSiPP200 prototyping services is anticipated by the first half of 2021”, said Joris Van Campenhout, Program Director Optical I/O at imec.
