DATA
SHEET
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.
2. For the purpose of these tests, IFis DC current.
3.. Threshold current varies as (TA– TO)2. It may either
increase or decrease with temperature, depending upon
relationship of TAto TO. The magnitude of the change is
proportional to the threshold at TO.
4. Slope efficiency is defined as ∆PO/∆IF.
5. Beam divergence is defined as the total included angle
between the half intensity points.
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.

ADVANCED OPTICAL COMPONENTS
Finisar’s ADVANCED OPTICAL COMPONENTS division was
formed through strategic acquisition of key optical compon-
ent suppliers. The company has led the industry in high
volume Vertical Cavity Surface Emitting Laser (VCSEL) and
associated detector technology since 1996. VCSELs have
become the primary laser source for optical data communi-
cation, and are rapidly expanding into a wide variety of sensor
applications. VCSELs’ superior reliability, low drive current,
high coupled power, narrow and circularly symmetric beam
and versatile packaging options (including arrays) are enabling
solutions not possible with other optical technologies.
ADVANCED OPTICAL COMPONENTS is also a key supplier of
Fabrey-Perot (FP) and Distributed Feedback (DFB) Lasers, and
Optical Isolators (OI) for use in single mode fiber data and
telecommunications networks
