PURPOSE:To enhance optical coupling ratio of semiconductor laser diodes being employed in an optical connector for transmitting optical information. CONSTITUTION:The inventive system comprises edge emission semiconductor laser diodes 10a, 10b having different pumping wavelengths between polarization modes in two perpendicular directions where each laser diode emits light in short wavelength polarization mode, an optical system arranged to receive light in long wavelength polarization mode, and a half wavelength plate 12 for rotating a polarized light from one semiconductor laser diode by 90 deg. and delivering thus rotated polarized light to the other semiconductor laser diode. |
