FJORD

The SLD broadband light source

FJORD is the SLD broadband light source designed and developed by Pyroistech to provide a personalized spectral response in the NIR to the applications of the most demanding users. SLDs are also known as SLEDs o superluminescent diodes, and their operation is based on amplified spontaneous emission (ASE), also called superluminescence. Pyroistech offers the possibility of combining up to 8 modules to choose from high power SLDs, as well as adding an extra touch screen or USB connection to control the power of each SLD individually. Its compact, silent and sturdy design allows its integration in whatever type of application, covering a wide range of possibilities, from optical laboratories, fiber optics testing, Bragg grating interrogation, tomography, or industrial sensors among others.


Characteristics:

  • Configurable spectral bandwidth (up to 8 different SLD available from the table below).
  • Max. optical power (fiber 8μm): 5dBm*

Examples of application

LPFG inscription monitoring
LPFG inscription monitoring

In this setup, LPFG interrogation is performed using a FJORD broadband light source as excitation at the input of the fiber and collecting the optical power at the output using an optical spectrum analyzer. The analyzer permits to measure the resonant wavelength location and the band attenuation.
