Custom Optical Integration for High-Power Isolator Advanced Photonics Solutions by KernsTech
Project Background & Customer Challenge
A global photonics company needed a high-power fiber isolator with a fully custom optical function—something no standard product could deliver. The challenge was integrating a unique optical element inside the isolator while maintaining ultra-high isolation, low insertion loss, and long-term reliability.
Technical Barriers
Tight Internal Space: The isolator housing’s internal tolerances were extremely limited.
Precision Optics: The core (Faraday rotator, polarizers, and beam paths) must be aligned to sub-millimeter accuracy.
Complex Cleanroom Assembly: High-power performance demands strict contamination control and alignment.
KernsTech’s Technical Highlights
Optical System Expertise:
All isolator designs are based on proprietary simulations, especially for wedge angles and polarization.Custom Internal Design:
