Abstract
An optical waveguide device 1 having optical fiber arrays 3a and 3b and a waveguide chip 2 connected to each other. Insertion holes 6a and 6b are provided for optical fiber holding members 5a and 5b comprising quartz glass or the like. Optical fiber cores of the optical fiber arrays 3a and 3b are inserted into the insertion holes 6a and 6b and are fixed with an adhesive material. Parts of covering optical fibers 4a and 4b are also fixed to apertures of the optical fiber holding members 5a and 5b with the adhesive material. According to the present invention, the optical fiber cores do not move inside the optical fiber arrays 3a and 3b in high-temperature or high-humidity environments. Accordingly, the use of the optical fiber arrays combined with the waveguide chip 2 provides a highly reliable optical waveguide device excellent in mechanical characteristics and transmission characteristics.
