Summary:An optical device (1) comprises a substrate (11), an optical waveguide (12), a laser diode (13), photodiodes (14a, 14b), and a filter (15). The substrate (11) is provided with a flat reference surface (16) and a V-groove (17) recessed from the reference surface (16). A pin (6) is fitted in the V-groove (17) of the device (1) and a V-groove (5) of a connector (2). The optical waveguide (12) is formed on the reference surface (16). The optical waveguide (12) is provided with a core (21) and a cladding (22). The core (21) extends along the reference surface (16). The laser diode (13) emits a signal light beam with a first wavelength toward the core (21) and the photodiode (14a), individually. The filter (15) transmits the signal light beam with the first wavelength and reflects a signal light beam with a second wavelength. The signal light beam reflected by the filter (15) is received by a photodiode (14b).
