The MAOP-L284CN from MACOM is a silicon photonic integrated circuit featuring four high bandwidth Mach-Zehnder modulators integrated with four lasers operating at 1270, 1290, 1310 and 1330nm. The device also features a CWDM multiplexer and each channel is said to operate at data rates of up to 28Gbit/s.
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.
