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.
