Abstract: PROBLEM TO BE SOLVED: To simplify constitution and to attain miniaturization by preparing a 1/4 wavelength plate which is arranged so that an optical axis tilts at a specified angle to polarization outgoing from a semiconductor laser and a means which leads the outgoing light passing through the 1/4 wavelength plate to the outside. SOLUTION: This optical module is composed of a semiconductor laser 11, a 1/4 wavelength plate 1, a lens 4 and a ferrule 5 holding the end of an optical fiber 3. An optical signal exiting from the semiconductor laser 11 passes through the 1/4 wavelength plate 1 and is led to the outside passing through the lens 4 and the optical fiber 3 which are means leading out the optical signal. The outgoing light from the semiconductor laser 11 is linear polarization in an X axial direction (Ex direction), and the 1/4 wavelength plate 1 is arranged so that an optical axis tilts at nearly 45 deg. to the linear polarization. At this time, when the linear polarization passes through the 1/4 wavelength plate 1, output becomes circular polarization because the optical axis of the crystal of the 1/4 wavelength plate 1 is made incident at azimuth 45 deg. to a main cross section.  And a polarizing direction of return light is orthogonally crossed with the polarizing direction of oscillation light of the semiconductor laser 11.
