Thursday, February 12, 2026 at 08:08 PM

Sony Semiconductor Solutions has developed a Single Photon Avalanche Diode (SPAD) depth sensor using germanium. This technology aims to provide low-power distance measurement capabilities specifically for AR devices by improving sensitivity to near-infrared light.

Context

Sony Semiconductor Solutions has developed a new germanium-based Single Photon Avalanche Diode (SPAD) sensor specifically engineered for the augmented reality (AR) market. By incorporating germanium onto a silicon substrate, the sensor achieves significantly higher sensitivity to near-infrared light compared to traditional silicon-only versions. This breakthrough enables high-precision 3D depth sensing and spatial mapping while maintaining the compact form factor and ultra-low power consumption required for lightweight, battery-dependent wearable glasses. The technology represents a major leap in efficiency, operating at a drive voltage of approximately 1.2V. For investors, this advancement reinforces Sony’s position as the market leader with over 50% share of the global image sensor industry. The ability to provide high-accuracy sensing with minimal thermal output is a critical requirement for the next generation of consumer AR hardware. This development positions Sony to dominate the spatial computing supply chain as mass-market hardware releases accelerate through 2026 and 2027.
