Lumentum Holdings Inc. operates as a global provider specializing in the manufacture and sale of advanced optical and photonic products. Its extensive operations span across the Americas, Asia-Pacific, Europe, the Middle East, and Africa. The company's business is structured into two primary divisions: Optical Communications (OpComms) and Commercial Lasers (Lasers). The OpComms division delivers essential components, modules, and integrated subsystems vital for transmitting video, audio, and data across high-capacity fiber optic networks. Its product portfolio encompasses a wide array of optical technologies, including tunable transponders, transceivers, and various laser, receiver, and modulator modules. This segment also provides sophisticated transport solutions like reconfigurable optical add/drop multiplexers (ROADMs), optical amplifiers, and optical channel monitors, alongside specialized components such as 980nm, multi-mode, and Raman pump lasers. Further offerings include optical switches, attenuators, photodetectors, various filters (e.g., gain flattening, isolators, wavelength-division multiplexing), arrayed waveguide gratings (AWGs), multiplexers/de-multiplexers, and integrated passive modules. Notable innovations within OpComms include the Super Transport Blade, which consolidates optical transport functionalities onto a single card, as well as vertical-cavity surface-emitting lasers (VCSELs), directly modulated and electro-absorption modulated lasers (DML/EAM), and laser illumination sources crucial for 3D sensing applications. Its client base spans the telecommunications, data communications, consumer electronics, and industrial sectors. Conversely, the Commercial Lasers segment specializes in providing a diverse range of lasers, including diode-pumped solid-state, fiber, diode, direct-diode, and gas lasers. These are primarily utilized in original equipment manufacturer (OEM) applications across various industries. Key markets and uses include sheet metal processing, general manufacturing, biotechnology, graphics and imaging, remote sensing, and precision machining. Established in 2015, Lumentum Holdings Inc. maintains its corporate headquarters in San Jose, California.
