Tunable Laser
Tunable lasers are used as standby devices
for WDM transmitters, perform wavelength
routing and conversion. Desirable features for
these applications i l d wide t i range,
th
li ti
include id tuning
spectral purity and rapid tuning dynamics.
VPIcomponentMaker offers unique time-
domain models to investigate all aspects of
tunable laser design, including tuning
dynamics and spectral purity. Interconnected
modules, that represent sections of an
g
p
,
integrated laser and external components, can
simulate many different tunable laser designs.
All-Optical (Re-)generation & Processing
Higher transmission rates demand circuits that
generate and process optical signals at l
t
d
ti l i
l t low
cost, preferably in the optical domain. Active
photonic circuits meet this need by providing
all-optical methods of generating, switching
and processing information at very high data
rates using gain saturation and fast
nonlinearities. VPIcomponentMaker was

especially designed to model the dynamics of
ultra-fast photonic circuits made from
interacting elements, bringing unique insight to
their operation.
Self-Pulsation i M lti S ti L
S lf P l ti in Multi-Section Lasers
Multi-section lasers present self-pulsations as
a result of instabilities induced by coupling
between saturable-absorption and high-gain
regions. Self-pulsation is likely to occur when
the carrier lifetime in highly pumped gain
sections is sufficiently longer than in the lesser
p p
pumped absorber sections.
VPIcomponentMaker models carrier dynamics
and nonlinear effects such as spectral hole
burning, carrier heating, and four wave mixing.
It also supports monitoring of temporal
oscillations of the carrier density in MQW and
SCH regions of different sections.
