From both offices in Canada and Taiwan (R.O.C.) Allied Scientific Pro offers high quality and cost effective VCSEL products and large production capacity: Following wavelengths are available single and multimode:  

  • 665nm (655 to 675nm)
  • 850nm  (830 to 860nm)

  Available in TO-46, Piranha-Single or Multi, Piranha-Flat Multi, Chip (High Power) Typical applications of VCSELs are:

  • Optical mouse for computers
  • Optical sensors
  • Optical encoders

  VCSELs have high performance and low cost advantages.  The key features are:

  • The structure can be integrated in two-dimensional array configuration.
  • Low threshold currents enable high-density arrays.
  • Surface-normal emission and nearly identical to the photo detector geometry give easy alignment and packaging.
  • Circular and low divergence output beams eliminate the need for corrective optics.
  • Passive versus active fiber alignment, combined with high fiber-coupling efficiency.
  • Low-cost potential because the devices are completed and tested at the wafer level.
  • Lower temperature-sensitivity compared to edge-emitting laser diodes.
  • High transmission speed with low power consumption.
