Vertical Cavity Surface Emitting Laser (VCSEL)
- 665nm (655 to 675nm)
- 850nm (830 to 860nm)
- Optical mouse for computers
- Optical sensors
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.
