## Summary

Lumentum (LITE) reported $1.5B revenue in FY2024, up 1% YoY. Leader in optical components and laser chips for data centers, 3D sensing, and telecom. HQ: San Jose, CA. Market cap ~$3B.

## Company Overview

Lumentum Holdings Inc. is a leading provider of optical and photonic products for telecom networks, data center interconnects, and 3D sensing applications, headquartered in San Jose, California. Spun off from JDS Uniphase (JDSU) in 2015, Lumentum reported revenues of $1.5B in fiscal year 2024 (ending June 2024). The company's products are critical enablers of modern communications infrastructure and consumer electronics.

Lumentum operates through two segments: Cloud & Networking (optical transceivers, ROADMs, coherent components for telecom and data center, ~55% of revenue) and Industrial Tech (diode lasers, fiber lasers, VCSELs for industrial/consumer use, ~45%). In the data center space, Lumentum supplies high-speed optical transceivers (400G, 800G) used in AI cluster networking. For 3D sensing, Lumentum is the primary supplier of VCSEL laser arrays for Apple's Face ID technology and LiDAR sensors — a position that made it heavily Apple-dependent (Apple was ~30-35% of revenue at peak).

Lumentum has navigated significant disruption: Apple's shift toward in-house laser components reduced VCSEL revenue substantially, and the telecom equipment downturn (2023–2024) impacted its networking segment. However, the AI data center buildout and recovery in optical networking present recovery tailwinds. The company has invested in next-generation indium phosphide (InP) photonic integrated circuits (PICs) for 1.6T transceivers and beyond. Lumentum trades on NASDAQ (LITE) with a market cap of approximately $3B.

## Frequently Asked Questions

### What is Lumentum's annual revenue?
Lumentum reported $1.5B in revenue for fiscal year 2024 (ending June 2024), approximately flat year-over-year as telecom weakness offset recovery in data center optical components.

### What does Lumentum make?
Lumentum makes optical transceivers and coherent components for telecom and data center networks, VCSEL laser arrays for 3D sensing (Apple Face ID), ROADM wavelength routing equipment, and industrial fiber lasers.

### What is Lumentum's stock ticker?
Lumentum Holdings trades on NASDAQ under ticker LITE.

### What is Lumentum's relationship with Apple?
Lumentum was Apple's primary supplier of VCSEL laser arrays used in iPhone's Face ID TrueDepth camera system and later LiDAR scanners. Apple represented 30-35% of revenue at peak, but Apple has been diversifying suppliers and developing in-house laser technology, reducing this dependency.

### Who are Lumentum's main competitors?
Lumentum's primary competitors are Coherent Corp. (II-VI), Acacia Communications (Cisco), Inphi (Marvell), and II-VI/Finisar in optical transceivers. In VCSELs, it competes with ams OSRAM and Sony Semiconductor.

### What is Lumentum's role in 3D sensing for consumer electronics?
Lumentum is a leading supplier of vertical-cavity surface-emitting lasers (VCSELs) used in 3D sensing modules for smartphones — most notably Apple's Face ID and TrueDepth camera systems that enable facial recognition and Animoji. VCSELs emit infrared light structured patterns that the depth sensor uses to map the precise 3D geometry of a face, enabling secure biometric authentication. Apple has been Lumentum's largest 3D sensing customer, making iPhone production cycles a significant variable in Lumentum's quarterly revenue. The Industrial Tech segment, which includes VCSELs and other diode lasers, represents approximately 45% of total revenue.

### What is Lumentum's ROADM product and why does it matter?
Reconfigurable Optical Add-Drop Multiplexers (ROADMs) are network nodes in fiber-optic telecom infrastructure that route different wavelengths of light (each carrying separate data streams) through networks without converting signals to electrical form — enabling flexible, software-defined routing of hundreds of gigabits per second across long-haul fiber networks. Lumentum is one of the primary suppliers of ROADM components to major telecom equipment makers like Ciena, Infinera, and Nokia, whose systems are deployed in backbone telecom networks worldwide. ROADM products are part of the Cloud & Networking segment alongside coherent optical transceivers.

### What is Lumentum's financial profile and competitive position?
Lumentum reported $1.5 billion in fiscal year 2024 revenue (ending June 2024), with the business divided between Cloud & Networking (optical transceivers, ROADMs, coherent components for telecom and data center interconnect) and Industrial Tech (3D sensing VCSELs, diode lasers, fiber lasers). The company faces competition from Coherent Corp, II-VI, and Finisar in optical transceivers, and from AMS-OSRAM and Princeton Optronics in VCSEL-based 3D sensing. Lumentum's financial results are meaningfully influenced by Apple's product cycle, as iPhone Face ID production drives seasonal VCSEL demand peaks.
