    Abstract: The present invention provides a bi-directional optical module with an optical isolator to prevent stray light from entering the laser diode (LD). The module includes a distributed feedback LD (DFB-LD), a photodiode (PD), a wavelength division multiplexed (WDM) filter, and a polarization independent isolator placed between the WDM filter and the optical fiber. The stray light emitted from the LD and scattered by optically discontinuous interface is prevented from returning to the LD by the isolator. Although the isolator shifts the optical axis of the receiving optical signal emitted from the optical fiber, the PD with a wide optical sensitive surface may receive almost whole portion of the receiving optical signal.
