The HFE4082-321 is a high-performance 850 nm VCSEL (Vertical Cavity Surface-
Emitting Laser) packaged for high-speed data communications. This product combines
all the performance advantages of the VCSEL 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 each VCSEL. In addition, built-in power attenuation
reduces the effective slope efficiency. These combined features simplify design for high
data rate communication and eye safety. The HFE4082-321 is a high radiance VCSEL,
designed to convert electrical current into optical power that can be used in fiber optic
communications and other applications. As the current increases above threshold, the
light intensity increases proportionally. The HFE4082-321 is designed to be used with
inexpensive silicon or gallium arsenide detectors (see HFD3081-108), 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 EML (Emitter Coupled Logic) gates possible and eases driver design.
The HFE4082-321 is designed to interface with 50/125 and 62.5/125 um multimode
fiber. They produce circularly symmetric, non-astigmatic, narrow divergence beams that,
with appropriate lensing, fiber couple all of the emitter power.
