Fiber Isolators for Broadband SLDs
Free-Space Isolators
Custom Isolators

Features

  • Flat Isolation over a 100 nm and 150 nm Wavelength Range
  • Ideally Suited for Use with SLDs
  • Unterminated Fiber Pigtails, Connectors Available by Contacting Tech Support
  • Polarization-Independent Design
  • Custom Isolators Available (See the Custom Isolators tab)

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 unterminated fiber ends.

  • Specified power rating is for the isolator. Proper laser termination is critical. Not recommended for high-power pulsed applications.
  • The maximum power specification represents the maximum power for the combined forward and reverse directions. Therefore, the sum of the powers in the forward and reverse directions cannot exceed the maximum power specification.
  • Isolation varies with wavelength; see the Performance Graphs for details. Isolation is also temperature dependent.

OEM and Non-Standard Isolators

In an effort to provide the best possible service to our customers, Thorlabs has made a commitment to ship our most popular free-space and fiber isolator models from stock. We currently offer same-day shipping on more than 90 isolator models. In addition to these stock models, non-stock isolators with differing aperture sizes, wavelength ranges, package sizes, and polarizers are available. These generally have the same price as a similar stock unit. If you would like a quote on a non-stock isolator, please fill out the form below and a member of our staff will be in contact with you.

Thorlabs has many years of experience working with OEM, government, and research customers, allowing us to tailor your isolator to specific design requirements. In addition to customizing our isolators (see the OEM Application Services list to the right), we also offer various application services.

  • Custom Faraday rotators, for use in the 244 to 5000 nm range, are also available.
  • The maximum power specification represents the maximum power for the combined forward and reverse directions. Therefore, the sum of the powers in the forward and reverse directions cannot exceed the maximum power specification.

Free-Space Isolators

We are able to provide a wide range of flexibility in manufacturing non-stock, free-space isolators. Almost any selection of specifications from our standard product line can be combined to suit a particular need. The table to the right shows the range of specifications that we can meet.

We offer isolators suitable for both narrowband and broadband applications. The size of the housing is very dependent on the desired maximum power and aperture size, so please include a note in the quote form below if you have special requirements.

 

Faraday Rotators

We can also offer Faraday rotators which rotate the polarization of incoming light by 45° ±3°. These are similar to our isolators but with the polarizers at each end removed. They are available with center wavelengths from 244 to 5000 nm.

  • For wavelengths shorter than 633 nm, we recommend using our free-space isolators in conjunction with our modular FiberBench accessories. Please contact Technical Support for more information.
  • The maximum power specification represents the maximum power for the combined forward and reverse directions. Therefore, the sum of the powers in the forward and reverse directions cannot exceed the maximum power specification.

Fiber Isolators

Thorlabs is uniquely positioned to draw on experience in classical optics, fiber coupling, and isolators to provide flexible designs for a wide range of fiber optic specifications. Current design efforts are focused on increasing the Maximum power of our fiber isolators at and near the 1064 nm wavelength. We offer models with integrated ASE filters and taps. The table to the right highlights the range of specifications that we can meet.

Mounted Isolator

The fiber used is often the limiting factor in determining the Maximum power the isolator can handle. We have experience working with single mode (SM) and polarization-maintaining fibers (PM); single-, double- and triple-clad fibers; and specialty fibers like 10-to-30 µm LMA fibers and PM LMA fibers.

In the spectral region below 633 nm, we recommend mounting one of our free-space isolators in a FiberBench system. A FiberBench system consists of pre-designed modules that make it easy to use free-space optical elements with a fiber optic system while maintaining excellent coupling efficiency. Upon request, we can provide select stock isolators in an optic mount with twin steel dowel pins for our FiberBench systems, as shown to the left.

We are also in the process of extending our fiber isolator capabilities down into the visible region. For more information, please contact Technical Support.
