Low-Profile Fiber Arrays

Low-profile angled fiber arrays direct light vertically through a reduced-height cap via total internal reflection on the array’s end face. Customers can specify the emission angle or the angle of the polished end face according to their application requirements.

Arrays can be equipped with single-mode (SM) or polarization-maintaining (PM) fibers and customized fiber pitch. The end face can optionally be coated with silver or gold to ensure total reflection under all conditions. The arrays are also available in variants suitable for cryogenic temperatures or ultra-high vacuum environments, offering high reliability in demanding optical setups.

Advantages 

• Compact low-profile design for vertical coupling
• Customizable emission or polishing angles
• Optional reflective coating (Ag/Au) for maximum efficiency
• Compatible with cryogenic and ultra-high vacuum environments
• Reliable performance with SM or PM fibers

Applications

• Coupling to on-chip grating couplers
• Photonic integrated circuits (PICs) testing
• Quantum optics and cryogenic experiments
• Fiber-to-chip interconnects in data/telecom
• Compact optical sensing modules
