Overview

Best-in-class DMLs for your high-reliability module applications

Lumentum manufactures indium phosphide (InP) directly-modulated lasers (DMLs) in our internal wafer foundry. These DMLs are based on the distributed feedback (DFB) diode lasers. With a DFB, a distributed Bragg reflector is used to accurately lock to the desired wavelength. With the DML, the laser power is directly modulated with a current driver chipset. These are typically silicon-germanium-based high-speed electronic drivers. Lumentum offers multiple data rates and wavelengths including - 100G QSFP28 PSM4/25G SFP28 LR, 100G QSFP28 CWDM4/25G SFP28 BiDi 10 km reach, and 100G QSFP28 LR4 for use in data center applications.
