This product is a high-performance 850nm VCSELs (Vertical Cavity Surface-
Emitting Lasers) designed for high-speed data communications and packaged
with a custom designed power monitor diode. The power monitor diode can
be used with appropriate feedback control circuitry to set a maximum power
level for the VCSEL. These combined features simplify design for high data rate
communication and eye safety.
The device is designed to convert electrical current into optical power that can
be used in fiber optic communications and other applications. As the current
varies above threshold, the light intensity increases proportionally.
It is designed to be used with inexpensive silicon or gallium arsenide detectors,
but excellent performance can also be achieved with some indium gallium
arsenide detectors.
The low drive current requirement makes direct drive from PECL (Positive
Emitter Coupled Logic) or ECL (Emitter Coupled Logic) gates possible and
eases driver design.
VCSELs produce circularly symmetric, non-astigmatic, narrow divergence
beams that, with appropriate lensing, fiber couple all of the emitter power. This
LC TOSA product is pre-aligned and focused fiber optic transmitters designed
to interface with 50/125 and 62.5/125µm multi-mode fiber.
