VCSELs Increase Power and Wavelength for 3D Sensing
For vertical-cavity surface-emitting lasers (VCSELs), the future looks bright — because their performance is rising while their price is falling. On the horizon is also a move from near-IR to shortwave IR wavelengths. These trends will help VCSELs meet a surging demand that is driven by their increasing use in 3D sensing applications (Figure 1). Figure 1. The VCSEL market forecast for 2021 to 2026, according to a 2021 Yole Développement report on market trends for the
