Fiber Isolators for Broadband SLDs




  • Flat Isolation over a 100 nm and 150 nm Wavelength Range
  • Wavelength Ranges Covering 790 to 970 nm
  • Ideally Suited for Use with SLDs

Features

  • Flat Isolation over a 100 nm and 150 nm Wavelength Range
  • Ideally Suited for Use with SLDs
  • Bare Fiber Pigtails, Connectors Available on Request
  • Polarization-Independent Design

Fiber isolators protect light sources from back reflections and signals that can cause instabilities and damage. They are designed to block light traveling into the source while allowing light to exit the source with minimal loss. The IO-F-SLD Series Polarization-Independent Broadband Fiber Isolators are specifically designed for use with superluminescent diodes (SLDs) such as our SLD Series. Typical fiber isolators have a narrow isolating wavelength range with a peak isolation of about 33 dB. These isolators are designed for flat isolation over a broad wavelength range of either 100 nm or 150 nm depending on the model but have a lower isolation of 23 to 32 dB (see the graph below). This makes them an ideal choice for broad-spectrum devices like SLDs. These polarization-independent models are designed for use with CW light sources only and come with 780HP single mode fiber with bare fiber ends.

  • Specified power rating is for the isolator. Proper laser termination is critical. Not recommended for high-power pulsed applications.
  • Isolation varies with wavelength; see the Performance Graphs for details. Isolation is also temperature dependent.
