Optical fiber-fixing substrate, method of producing the same and optical device |
摘要 |
The present invention aims to prevent formation of defect or break-off at ridges of fixing grooves of optical fiber-fixing substrates, when an optical fiber is received in the fixing groove or when an end surface of the substrate is polished by a grinding work. For that purpose, the ridges of the fixing grooves of the substrate have a curvature of radius of not less than 5 mu m over the entire portion of the ridges viewed in the lateral cross-sectional view of the fixing grooves. Preferably, the bottoms of the fixing grooves of the substrate have a curvature of radius of not more than 5 mu m viewed in the lateral cross-sectional view of the fixing groove. The fixing grooves may be produced by press forming.
