FAU Glass for CPO: V-Groove Alignment, Coupling Loss and Drawing Requirements
How V-groove substrates and glass lids position fiber arrays for CPO and photonic chips. Learn coupling-loss assumptions, tolerance stacks, inspection and RFQ requirements.
B270 Superwhite Glass Precision Processing: Cutting, Edging & Quality Control
B 270 is often treated as an easy material to cut: moderate hardness, low breakage, fast scoring. But a conforming dimension does not make a conforming part — where are chips, TTV, form and surface defects actually decided? A process note for optical window designers and buyers.
Precision Glass Strips, Cover Plates and Shims in Optical Communication Modules
How glass strips, cover plates and shims affect assembly accuracy in optical modules: thickness, TTV, parallelism, flatness, edge quality, material selection and batch control.
Through-Glass Via (TGV) Drilling: Hole Geometry, Defects and Inspection
Explore glass TGV drilling, through-hole defects, hole circularity, waist diameter, thickness effects, laser-assisted etching and precision inspection.
V-Groove Glass Substrates for Fiber Arrays: Geometry, Materials and Inspection
How V-groove geometry, glass selection, lid fit, assembly and inspection affect fiber-array alignment. A practical drawing and RFQ guide for engineers.
