V-Groove Substrate 12CH (Silicon)
Precision V-groove substrate, 12 channels on a silicon substrate, channel pitch 127μm/250μm, adjacent groove pitch accuracy ±0.5μm, groove parallelism better than ±0.1°. Sizes customized to drawing.
Description
The V-Groove Substrate 12CH (Silicon) is the core base component of a fiber array. Using a precision grooving process, we machine 12 V-shaped alignment grooves into a low-expansion silicon substrate or silicon to align and fix bare fibers precisely — the key material for reducing coupling loss in planar lightwave circuit (PLC) splitters, arrayed waveguide gratings (AWG) and similar devices.
Product Features
- Channel count 12CH on a silicon substrate, channel pitch selectable 127μm or 250μm; higher counts customized to drawing
- Adjacent groove pitch accuracy up to ±0.5μm; groove parallelism better than ±0.1°
- Substrate material: silicon
- Length, width and thickness customized to customer drawing; parallelogram and other profiled structures available
- The 12-channel structure suits high-density parallel coupling.
