Product Specification
1.25Gbps VCSEL Component, TO-46
HFE4083-322
PRODUCT FEATURES
• Designed for drive currents between 5
and 15 mA
• Optimized for low dependence of
electrical properties over temperature
• High speed >1 GHz
• Two different laser/photodiode
polarities
• Un-attenuated window
• Packaged with a photo-detector
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.

Notice
Stresses greater than those listed under “Absolute Maximum Ratings”
may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other
conditions above those indicated in the operations section for
extended periods of time may affect reliability.
Notice
The inherent design of this component causes it to be sensitive to
electrostatic discharge (ESD). To prevent ESD-induced damage
and/or degradation to equipment, take normal ESD precautions when
handling this product

II. Electro-Optical Characteristics
Notes:
1. Reliability is a function of temperature, see www.finisar.com for details.
2. Operating power is set by the peak operating current I

3. For the purpose of these tests, I

4. Threshold current varies as (T

)

. It may either increase or decrease with temperature,
depending upon relationship of T
A
to T
O
. The magnitude of the change is proportional to the
threshold at T

.
5. Slope efficiency is defined as ∆P

/∆I
F
.
6. Rise and fall times specifications are the 20% - 80%. Most of the devices will measure <200ps fall
time. Rise and fall times are sensitive to drive electronics.
7. Beam divergence is defined as the total included angle between the 1/e
2
intensity points.
8. To safeguard the VCSEL from current spike damage, short the VCSEL anode and cathode to each
other during photodiode BVR verification testing. Additionally to safeguard the PIN photodiode,
limit the photodiode reverse voltage in accordance with the absolute maximum rating.
