PRELIMINARY DATA
SLD (Super Luminescent Diode)
L8414-04
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.
