The HFE4083-322 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. These combined features simplify design
for high data rate communication and eye safety. The HFE4083-322 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 HFE4083-322 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 HFE4083-322 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.
