Abstract
An optical waveguide device having an optical waveguide chip, first and second adapters, and an optical fiber plug. The optical waveguide chip has an optical waveguide structure having a connection end, and an end surface of the chip is flush with the connection end. The first adapter is fixed to the chip, and has an outer surface set in predetermined positional relation with the connection end. The second adapter has an inner surface including a first region and a second region, and is detachably mounted to the first adapter so that the outer surface of the first adapter comes to close contact with the first region. The optical fiber plug has an optical fiber having an excitation end and a ferrule in which the optical fiber is inserted and fixed. The optical fiber plug is detachably mounted to the second adapter so that the outer surface of the ferrule comes to close contact with the second region. When the second adapter is mounted to the first adapter, and the optical fiber plug is mounted to the second adapter, the connection end of the optical waveguide structure of the chip and the excitation end of the optical fiber are optically coupled.
