Product Description

Product Description

The Kerns Technology Polarization Insensitive High Power Isolator is a robust passive optical component designed to protect high-power light sources by blocking reverse-propagating light (back-reflections/backscatter) while transmitting forward signals—regardless of input polarization state.

Optimized for 633nm (customizable wavelengths) and up to 1W (or higher) continuous-wave (CW) power, this isolator delivers key performance: typical isolation of 25-30dB, low insertion loss (0.9dB typical), and minimal polarization-dependent loss (≤0.15dB). Its compact C40 package, HI 780 fiber compatibility, and wide operating temperature (-5~+50°C) make it ideal for high-power laser, measurement, and industrial optical systems.

Product Features

1. Polarization Insensitivity

Max polarization-dependent loss ≤0.15dB ensures consistent performance across all input polarization states—eliminating the need for polarization control in diverse systems.

2. High Power Handling

Supports up to 1W CW power (customizable to higher levels) to meet the demands of high-power laser setups, outperforming standard isolators with <500mW capacity.

3. Low Loss & High Isolation

Typical insertion loss: 0.9dB (≤1.3dB max) minimizes signal attenuation
Typical isolation: 25-30dB (≥23dB min @23°C) effectively blocks reverse light to protect light sources.

4. Flexible Customization

Wavelength: 633nm (default) or custom (e.g., 1064nm, 1550nm)
Power capacity: 1W (default) or tailored to system requirements
Fiber/connector options: HI 780 fiber, 250μm bare fiber/900μm loose tube, FC/SC connectors (UPC/APC)

5. Robust Mechanical Design

Compact C40 package (optimized for integration)
High tensile load (5N) ensures durability in industrial deployment

Product Applications

This polarization insensitive high power isolator is widely used in:

High-Power Lasers: Protects laser diodes from back-reflections in material processing, medical laser, and scientific research systems.
Optical Measurement Equipment: Ensures signal integrity in high-power spectroscopy and laser characterization setups.
Industrial Optical Systems: Stabilizes performance in fiber optic sensing and high-power optical communication links.
Scientific Research: Supports polarization-free light transmission in quantum optics and photonics experiments.

FAQs

Q1: What is the advantage of polarization insensitivity?

A1: It ensures stable performance regardless of the input signal’s polarization state—critical for systems where polarization cannot be controlled (e.g., high-power lasers, multi-component optical links).

Q2: Can this isolator be customized for higher power?

A2: Yes. We offer standard 1W capacity and can design high-power versions (up to 10W CW) with reinforced packaging and thermal management for specialized applications.

Q3: How do connectors affect performance?

A3: With connectors, insertion loss increases by 0.3dB, return loss decreases by 5dB, and extinction ratio drops by 2dB. We recommend factory-aligned connectors (slow axis/key alignment) for optimal results.

Q4: Is this isolator compatible with other fiber types?

A4: The default fiber is HI 780, but we can customize it to match other fiber specifications (e.g., SMF-28e, LMA fibers) based on your system’s compatibility needs.
