PROBLEM TO BE SOLVED: To provide a package BiD equipped with a polarization independent optical isolator having a function that prevents reflection return light from entering an LD. SOLUTION: The package BiD1 includes: an LD 32 for outputting transmission light to an optical fiber; a PD 36 for receiving reception light that is emitted by the optical fiber and that has a wavelength different from the transmission light; a wavelength multiplexing/demultiplexing filter 33 that reflects the transmission light and transmits the reception light or reflects the reception light and transmits the transmission light; and the polarization independent optical isolator 20 that is mounted between the wavelength multiplexing/demultiplexing filter 33 and the optical fiber.
