EXALOS launches 750nm SLEDs for biomedical applications

EXALOS of Schlieren, Switzerland has added a new 750nm product line to its family of powerful superluminescent light emitting diodes (SLEDs, which combine the spatial coherence of a laser diode with the temporal incoherence
of an LED).

Due to their high output power and large bandwidth, as well as high suppression of second coherence peaks, the 750nm SLEDs are suited for optical coherence tomography (OCT) and biomedical applications. Their spectra show a clean Gaussian shape with very low ripple values, claims
EXALOS. The advantages of SLEDs result in high resolution and fast scan times, it adds.

Typical values for the EXS7505-1411 are 3.0mW optical output power in a single-mode fiber and 21nm 3dB spectral bandwidth. The EXS7510-1411 achieves 5.0mW and 14nm. The standard product is delivered in a 14-pin DIL housing
with built-in thermo electric cooler (TEC) and monitor diode. Uncooled devices in TOSA housings are also available. Also suited for biomedical and OCT applications are EXALOS SLEDs emitting at wavelengths of 850nm and 1300nm.

EXALOS SLEDs target specific applications in four major markets:

· optical coherence tomography for medical
applications such as cornea and retina diagnostics;

· fiber-optic gyroscopes for applications
such as avionics, aerospace and navigation;

· optical channel monitors, chromatic and
polarization mode dispersion, and passive component characterization in test equipment for telecom and datacom systems;

· fiber-optic sensors for civil structure monitoring such as bridges and oil pipelines as well as temperature, pressure, and electrical current measurements.

All devices are BELLCORE GR-468-CORE and MIL-STD-883 qualified.
