Fiber Optics & Photonics Industries

Microstructural analysis supports the reliability of optical fibers, waveguides, and thin‑film photonic devices by revealing interfaces, defects, and process quality. Preparation challenges include sectioning brittle glass fibers without inducing microcracks, preserving claddings and coatings, and polishing delicate multilayer stacks (e.g., Si, GaAs, InP) to optical‑grade, scratch‑free finishes without subsurface damage. Allied High Tech Products provides low‑damage precision sectioning, rigid fixturing for end face and cross‑section preparation, and controlled grinding/polishing workflows— including chemo mechanical steps (e.g., colloidal silica) — to deliver repeatable, metrology‑ready surfaces for accurate optical and materials characterization.
