Photonics and Quantum Technology Expansion: The Primary Growth Engine

The report identifies the explosive growth of the global photonics and quantum technology sectors as the paramount driver for SPAD demand. With quantum communication systems alone accounting for approximately 38 % of total SPAD applications, the correlation is direct and substantial. The global quantum‑secure communications market is projected to exceed US$ 45 billion by 2030, fueling an unprecedented need for single‑photon detection capabilities.

“The concentration of advanced lidar manufacturers and autonomous vehicle platforms in North America and Europe, which together consume about 42 % of global SPAD volumes, is a key factor in the market’s dynamism,” the report states. With worldwide investments in autonomous‑driving technologies surpassing US$ 120 billion through 2030, the demand for compact, high‑efficiency SPAD arrays is set to intensify, especially as automotive lidar shifts toward solid‑state architectures requiring sub‑nanosecond timing jitter.
