Indie Semiconductor Unveils 399 nm UV DFB Laser for Ytterbium‑Based Quantum Computing

March 24, 2026

Indie Semiconductor announced a new ultraviolet distributed‑feedback laser diode that emits a single‑frequency beam at 399 nm, the exact wavelength required to drive transitions in cooled ytterbium atoms used in many quantum‑computing platforms.

The laser, model ELA350028, delivers high spectral purity without the need for external cavity gratings or frequency‑doubling optics, simplifying system design and reducing cost for quantum‑computer builders.

This launch extends Indie’s photonics lineup beyond its earlier LXM‑U and narrow‑linewidth visible DFB lasers, marking a strategic shift toward high‑growth markets such as quantum computing, which is projected to reach $4.24 billion by 2030 from $1.42 billion in 2024.

Indie’s Q4 2025 results—$58 million in revenue and a non‑GAAP loss per share of $0.07—highlight the company’s current profitability challenges, yet the new product signals a diversification effort that could open additional revenue streams beyond its core automotive ADAS business.

Management emphasized the importance of the new laser: VP Philipp Vorreau said, “Highly stable laser sources without mode hopping are a critical building block for atom‑cooled and trapped‑ion quantum‑computing platforms.” CEO Donald McClymont added that the company’s expansion into quantum computing and humanoid robotics is part of a broader strategy to drive growth.

The announcement underscores Indie’s commitment to innovation and its pursuit of a more balanced portfolio, positioning the company to capture a share of the rapidly expanding quantum‑computing market while continuing to serve its existing automotive customers.
