Coherent optics extend AI clusters across halls, campuses, and regions. Lumentum’s driver-modulators provide high bandwidth and excellent linearity to support advanced modulation formats. The Mach–Zehnder (MZ) structures integrate semiconductor optical amplifiers (SOAs) that can reduce insertion loss or balance power between the two polarizations. This configuration enables transceiver designs that use a single laser split between the transmitter and the local oscillator, simplifying their architecture.
