Frequently Asked Questions

What is a 1064nm Polarization Insensitive Isolator and how does it work?

A 1064nm Polarization Insensitive Isolator is an optical device designed to allow light to pass in one direction while blocking it in the reverse direction, regardless of the light's polarization state. It utilizes the Faraday Effect in a magneto-optical crystal to achieve this non-reciprocal behavior, effectively eliminating back reflection and back scattering in fiber optic systems.

What are the main applications of the DK Photonics 1064nm Polarization Insensitive Isolator?

This isolator is widely used in fiber optic communication systems such as EDFAs (Erbium-Doped Fiber Amplifiers), Raman amplifiers, DWDM systems, fiber lasers, and transmitters. Its primary function is to suppress back reflection and back scattering, thereby improving system performance and protecting sensitive components.

What are the key features and benefits of the DK Photonics 1064nm Polarization Insensitive Isolator?

Key features include low insertion loss, high isolation, optical path epoxy-free design, low polarization dependent loss (PDL) and polarization mode dispersion (PMD), high reliability, and excellent temperature stability. These features ensure high performance, durability, and suitability for demanding optical applications.

What is the maximum optical power handling capability of the 1064nm Polarization Insensitive Isolator?

For the standard 1064nm isolator, the recommended average power handling is less than 200mW for single-stage devices and less than 100mW for dual-stage devices. For higher power requirements, DK Photonics offers a 1064nm TGG High Power Isolator. For pulse applications, it is important to inform the manufacturer of the pulse energy and peak power.

How does the presence of connectors affect the performance of the isolator?

When connectors are added to the isolator, the insertion loss (IL) increases by 0.3dB and the return loss (RL) decreases by 5dB compared to devices without connectors. For optimal performance, it is recommended to specify your connector requirements when ordering.

Can the DK Photonics 1064nm Polarization Insensitive Isolator be customized for specific requirements?

Yes, DK Photonics offers custom isolators tailored to specific needs, including custom fiber pigtails, different operating wavelengths, and higher power handling capabilities. Customers are encouraged to provide detailed specifications or contact DK Photonics for custom solutions.

What should I consider when ordering or specifying a 1064nm Polarization Insensitive Isolator?

When ordering, provide the correct part number (P/N) and detailed description, including connector type, fiber type, and any special requirements. If you require connectors, avoid choosing a 250μm bare fiber pigtail. For pulse applications, specify the pulse energy and peak power to ensure the isolator meets your needs.
