Advanced Technology VCSEL
Chip
The SV3637 combines 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. Custom packaging designs are also available. The
different packages are for different applications both in the datacom market as
well as in the sensor market.

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

NOTES
1.
Reliability is a function of temperature, see
www.finisar.com/aoc.php for details.
For the purpose of these tests, IF is DC current.
4.
5.
Slope efficiency is defined as
∆P
O/∆IF.
Beam divergence is defined as the total included angle
between the half intensity points.
2.
3.. Threshold current varies as (TA – TO)
2
. It may either
increase or decrease with temperature, depending upon
relationship of TA to TO. The magnitude of the change is
proportional to the threshold at TO.
TYPICAL PERFORMANCE CURVES
Emitted Power vs. Current: Power varies approximately
linearly with current above threshold.
Threshold Current vs. Temperature: Threshold current varies
parabolically with temperature; thus it can be nearly constant
for a limited temperature range.
