OPTICAL DEVICE AND PRODUCTION METHOD THEREFOR

摘要

An optical device (10A) which has a structure that guides the reflection light of light (L) passing through an optical fiber array (24) having at least one optical fiber (22) to the outside of the optical fiber array (24), and which comprises the above optical fiber array (24), another optical fiber array (68) having at least one optical fiber (66), and a reflection member (90) disposed between the end face (40) of the optical fiber array (24) and the end face (80) of the optical fiber array (68), wherein the reflection member (90) is fixed between the optical fiber arrays (24, 68) via adhesives (94, 98) as reflectance matching layers.
