Called an L-PIC – laser photonic integrated circuit – by MACOM, the part links to a standard single mode optical fibre and includes integrated tap detectors for alignment, system initialisation and closed loop control.
Using MACOM’s Etched Facet Technology, lasers are attached to the silicon PIC, whose die measures 4.1 x 6.5mm. The only optical requirement for implementing the device into QSFP28 transceiver applications is an optical fibre aligned to the output edge coupler.
