Case Study for Bidding
Time: April 2024
Supplier: Thorlabs, Inc. (U.S.)
Buyer: Nokia Bell Labs (U.S.)
Product: 1,550 nm dual-stage polarization independent isolator cores for fiber amplifier modules
Quantity: 240,000 units
Contract Value: USD 22.8 million
Delivery Timeline: March 2025
Case Study for End Using
End User: Huawei Technologies Co., Ltd. (China)
Application: Integrated into erbium-doped fiber amplifiers (EDFAs) for backbone optical communication networks.
Installation Location
Installed between the pump laser diode and gain fiber module.
Aligned with polarization-maintaining fiber connectors.
Housed in sealed micro-packages for vibration and temperature stability.
Purpose
Prevents back-reflected signals from destabilizing optical amplifiers.
Maintains high isolation under arbitrary input polarization.
Enhances system reliability in dense WDM fiber links.
Effect
Improved amplifier signal-to-noise ratio by 17%.
Reduced reflection-induced power fluctuation by 25%.
Enhanced long-term stability in high-power optical transmission systems.
Alternative Devices
Polarization-dependent isolators offer lower cost but cannot maintain uniform isolation with unpolarized or random light.
Therefore, Polarization Independent Isolator Cores remain critical for modern optical systems requiring stable, polarization-insensitive performance.
During the testing of a high-power laser communication system, a photonics company in Germany encountered signal instability caused by back-reflections from optical components. These reflections induced polarization changes, degrading transmission efficiency and causing thermal drift in the laser cavity. To solve this, the engineering team integrated Polarization Independent Isolator Cores into the optical path. These cores prevented back-propagating light from re-entering the source, maintaining stable power and wavelength regardless of input polarization. By adopting these isolators, the company eliminated feedback noise, improved long-term laser reliability, and achieved consistent data transmission over extended operating cycles-critical for satellite and fiber-optic communication systems.
