Abstract
Cameras are omnipresent in our daily lives, with several billions image sensor units deployed annually. The imaging revolution was possible with the introduction of CMOS (complementary metal-oxide-semiconductor) technology and streamlining the manufacturing process based on the semiconductor ecosystem. CMOS image sensors (CIS) are relying on light detection by a silicon photodiode, which is perfectly suited for replicating human vision (visible wavelength range) and beyond (e.g. NIR – near infrared or UV - ultraviolet). At the same time, longer wavelengths such as short-wave infrared (SWIR) are inaccessible by Si due to the energy bandgap, setting the cut-off wavelength at around 1100 nm.
