These products are high-performance 850nm VCSELs (Vertical Cavity Surface-Emitting Lasers) designed for high-speed data
communications and packaged 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 the VCSEL. These combined features simplify design for high data rate
communication and eye safety.
These products are high radiance VCSELs designed to convert electrical current into optical power that can be used in fiber optic
communications and other applications. As the current varies above threshold, the light intensity increases proportionally.
These products are designed to be used with inexpensive silicon or gallium arsenide detectors, but excellent performance can also be
achieved with some indium gallium arsenide detectors (see HFD3381-002 and HFD3381-102 product data sheets).
The low drive current requirement makes direct drive from PECL (Positive Emitter Coupled Logic) or ECL (Emitter Coupled Logic)
gates possible and eases driver design.
VCSELs produce circularly symmetric, non-astigmatic, narrow divergence beams that, with appropriate lensing, fiber couple all of the
emitter power. These SC TOSA products are pre-aligned and focused fiber optic transmitters designed to interface with 50/125 and
62.5/125µm multi-mode fiber

Notes:
1) Reliability is a function of temperature, see
www.honeywell.com/VCSEL
for details.
2) For the purpose of these tests, I
F
is DC current.
3) Threshold current varies as (T
A
– T
O
)
2
. 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
O
.
4) Slope efficiency is defined as
∆P
O
/∆I
F
.
5) To compute the value of Slope Efficiency at a temperature T, use the following equation:
η(T) ≈ η(25
o
C)*[1+(∆η/∆ T)*(T-25)]
6) Rollover is the power at which a further current increase does not result in a power increase.
7) Rise and fall times specifications are the 20% - 80%. Most of the devices will measure <135ps fall time. Rise and fall times are
sensitive to drive electronics.
8) To compute the value of Series Resistance at a temperature T, use the following equation:
R
S
(T)
≈
R
S
(25
o
C)*[1+(∆R
S
/ ∆T)*(T-25)]
9) Beam divergence is defined as the total included angle between the 1/e
2
intensity points.
10) These specifications are for the TO-46 component alone. Reflections introduced by any subsequent higher level assembly may
affect these values.
11) Monitor current tracking is defined as follows:
Deltrk
=
I
PD
(P
O
=
0.75mW) / 0.75mW
I
PD
(P
O
=
0.45mW) / 0.45mW
TYPICAL PERFORMANCE CURVES:
Emitted Power vs. Current:
Power varies approximately
Threshold Current vs. Temperature:
Threshold
linearly with current above threshold.
current varies parabolically with temperature; thus it can
be nearly constant for a limited temperature range.
