What Does VCSEL Stand For?

VCSEL stands for Vertical Cavity Surface Emitting Laser

VCSEL, or Vertical Cavity Surface Emitting Laser, is a type of semiconductor laser that emits light perpendicularly from its surface. It is characterized by its vertical cavity structure, which allows for efficient light emission and high modulation speeds. VCSELs are widely used in various applications, including optical communication, sensing technologies, and data transmission, due to their compact size, low power consumption, and cost-effectiveness.
