High-performance optical components built for mission-critical applications<\/h2>\n\n\n\n

At Inneos, we design and manufacture vertical-cavity surface-emitting lasers (VCSELs)<\/a> and PIN photodetectors that are optimized for performance, reliability, and integration into demanding environments \u2014 from aerospace and defense systems to advanced medical and industrial platforms.<\/p>\n\n\n\n

Our component technologies form the foundation of our optical subsystems, but they\u2019re also available as discrete components for teams that need to build their own custom optical links.<\/p>\n<\/div><\/div>\n\n\n\n

What is a VCSEL?<\/h2>\n\n\n\n

A VCSEL (Vertical-Cavity Surface-Emitting Laser)<\/a><\/strong> is a type of semiconductor laser that emits light vertically from the surface of the chip \u2014 unlike edge-emitting lasers, which emit light from the side. VCSELs are compact, power-efficient, and ideal for short-reach, high-speed optical communication, low-power sensors, and very small optical modules.<\/p>\n<\/div>\n\n\n\n

These lasers convert electrical signals into optical signals, enabling fast, efficient communication over fiber \u2014 especially in systems where bandwidth, size, and EMI immunity matter.<\/p>\n\n\n\n

Inneos manufactures a variety of VCSELs:<\/p>\n\n\n\n
