“…VCSELs have considerable potential in three-dimensional (3D) sensing, such as in gesture recognition, face recognition, eye movement tracking, as well as in 3D photography and autofocusing [26,145]. The incorporation of VCSEL chips in smartphones is nowadays a reality [23].…”

“…The first ToF technology for 3D sensing is called a scanning ToF sensor, where single pixels are scanned one at a time with a VCSEL via short pulses. In a scanning ToF sensor, the pulse duration is always 1-10 ns, and the duty cycle is less than 10% [26,145,149,150]. VCSELs for such outdoor applications require a large optical output power for covering larger distances and still achieving a large signal-to-noise ratio [144].…”

Vertical-cavity surface-emitting lasers (VCSELs) are the ideal optical sources for data communication and sensing. In data communication, large data rates combined with excellent energy efficiency and temperature stability have been achieved based on advanced device design and modulation formats. VCSELs are also promising sources for photonic integrated circuits due to their small footprint and low power consumption. Also, VCSELs are commonly used for a wide variety of applications in the consumer electronics market. These applications range from laser mice to three-dimensional (3D) sensing and imaging, including various 3D movement detections, such as gesture recognition or face recognition. Novel VCSEL types will include metastructures, exhibiting additional unique properties, of largest importance for next-generation data communication, sensing, and photonic integrated circuits.
