An optical fiber array and optical device

Abstract

The utility model relates to optical communication technical field, concretely relates to a kind of optical fiber array and optical device.The optical fiber array includes bottom plate, several optical fibers, cover plate, first adhesive layer and second adhesive layer.Optical fiber includes adjoining bare fiber section and coating section, bare fiber section and part coating section are located on bottom plate;Cover plate is covered on bottom plate, and the side of bottom plate is provided with several optical fiber grooves, and optical fiber groove is used to accommodate the end of bare fiber section away from coating section;First adhesive layer is located between optical fiber groove and bottom plate, and covers bare fiber section in optical fiber groove;Second adhesive layer is located on bottom plate, and covers bare fiber section and coating section exposed outside optical fiber groove.The optical fiber array when carrying out end pile coupling, cover plate can not be placed downward, and bottom plate and ceramic substrate can be directly bonded and fixed.So, bottom plate can isolate protection second adhesive layer, avoid the fixing glue between bottom plate and ceramic substrate and second adhesive layer occur bonding, to prevent the optical fiber in second adhesive layer from being affected, appear loss.
