About sony vcsel
The Vertical Cavity Surface-Emitting Laser (VCSEL) is the key semiconductor laser technology used to make the displays of smart glasses and other wearable devices more compact and less power consuming. Sony is developing blue and green VCSELs with emission in the visible light range.
Optical communication Sony VCSEL are multi-mode lasers with wavelengths in the 850 nm band, used as light sources for short-range optical fiber communication.
Balancing high-speed characteristics and high reliability
Optical communication Sony VCSELs apply the characteristics of VCSELs. The Sony VCSEL are capable of direct modulation with low power consumption, and are used as light sources for optical communication modules in mega data centers.
