Optical Fiber Array Assembled
with Hermetic Feedthrough
Optical fibers are arranged with high precision using V grooves or capillaries. Multiple cores are also supported. Assembly with the stress-applied part of the polarized wave holding optical fiber aligned to a specified angle. An He leak amount of 1 × 10-9 atm・cc/sec or less is achieved by soldering or glass sealing of the kovar feedthrough for hermetic sealing.
Features
- Optical fiber assembly using a quartz capillary made by a unique slurry method or a V-groove base
- The number of cores, shapes, and optical fibers can be customized.
- Provided for optical device applications such as laser.
Ultra-compact feedthrough processed product
