Vertical Cavity Surface Emitting Laser (VCSEL)

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.
