PRELIMINARY DATA

Infrared Emitter with High Radiant Flux Density and Low Coherency

■FEATURES�

●High radiant flux density�

●Low coherency�

�

■APPLICATIONS�

●Optical fiber gyroscopes�

●Optical communication�

●Optical measurement systems

The super luminescent diode (SLD) is an infrared emitter that has the advantages of both the laser diode and the

LED; high radiant flux density and low coherency. The SLD was developed as a device that compensates for the

disadvantages of laser diodes such as their coherent noise and is therefore ideal for applications where a higher S/N

ratio is essential, for example in light-applied measurements and optical communications. A photodiode chip has also

been mounted within the same package for monitoring the SLD output.
