1650nm Superluminescent LED
Description
The Idealphotonics SLD-765 series is a
broadband SLED that operates in a
true inherent superluminescent mode.
This superluminescent property
generates broader band at higher drive currents in contrast to
other conventional SLEDs which are ASE-based, where high drive
tends to give
narrower band. Its
low coherence reduces
Rayleigh backscattering
noise. Coupled with
high power and large
spectral width, it
offsets photoreceiver noise and improves spatial resolution (in OCT) and
measurand sensitivity (in sensors).
The SLED is
available in 14-pin
BTF package. It
is compliance with
the requirements of Bellcore Document GR-468-CORE.
Enabled by Idealphotnics PICTM spread
spectra bandgap engineering
technology, future generations
of IDP SLEDs promise higher chip powers (up to 50mW possible), and broader spectral
bands (beyond 120nm).
Higher levels of
integration may feature integrated SLEDs
with phase modulators,
optical couplers and photodetectors into a
complete optical sensor chipset.
