To provide an optical waveguide which can be miniaturized, and to improve the utility efficiency of light by suppressing a ripple, an optical transmission device and an optical transmission system.
The optical transmission device 1 includes an optical waveguide 10 which transmits signal light incident from a light emitting element 21 and a dielectric filter 15 which reflects the signal light incident from the light emitting element 21. The optical axis of the signal light incident from the light emitting element 21 is set in a direction substantially vertical to the dielectric filter 15. The optical transmission device 1 is used as an optical sending device and an optical receiving device, and the optical sending device and the optical receiving device are connected by an optical fiber 2 to perform bidirectional optical transmission.
