Finisar Advanced Optical
Components has led the industry in high volume VCSEL technology since
introducing the first commercially available VCSEL in 1996. VCSELs
(Vertical Cavity Surface Emitting Lasers) are semiconductor lasers
which are effecting advances in optical communication, and sensor
applications.
For precision optical sensor
applications, Advanced Optical Components VCSELs’ superior reliability,
low drive current, high coupled power, narrow and circularly symmetric
beam and versatile packaging options (including arrays) are enabling
solutions not possible with other optical technologies.
VCSELs combine many of the
desired features of an LED and the advantages of a laser diode. The
VCSEL provides increased power output at low drive currents: as the
current increases above its threshold, the light intensity increases
proportionally. Packaging options include TO can, with and without
lensing, and 0805 small scale packaging.
Our reflective sensors use a
VCSEL in combination with a phototransistor to enable reflective
sensing applications. Packaging options include a TO-can package with
focusing optics, or a low cost, surface mount package.
Advanced Optical Components has
shipped more packaged VCSELs than any other company. Our world-renowned
R&D team is continually developing higher speeds and expanded
wavelengths. Technical support is available worldwide.
Advanced Optical Components has produced an array of application notes
and technical publications over the years, as well as the most comprehensive
VCSEL reliability analysis and data in the industry. Theses documents can be
found in the following libraries:
Reliability Data,
Technical Pubs, and
Application Notes,
or on the relevant product pages.
