V-Grooves and Fiber Arrays

Request for Quotation

Thank you for using our services

The fiber array manufacture is based on placing fiber in the high precision V-Groove Chip with another flat V-Groove Lid on top of it. The end face of the fiber array is optically polished, and on request available also with antireflection coating (ARC).

SQS Fiber Optic Arrays are manufactured and tested to the most rigorous industry standards. Their optical and mechanical performance meets IEC specifications and customer specified requirements.

Features:

Manufacturing according to customer requirements (standard drawing or custom solution)
High precision of fiber core positioning (core offset < 0,5 µm)
PM fiber available (polarization extinction ratio PER > 25 dB)
Single mode, multimode fiber
Custom solutions available
Atypical end face angle polishing available on request

Design:

From Single Channel up to 128 Channels
Many types of material (borosilicate glass, fused silica)

Applications:

Fibers to PLCs
Fibers to lens arrays
Detectors
