摘要： A method to manufacture an optical module is disclosed, wherein the optical module has an optically active device on a lead frame and a lens co-molded with the active device and the lead frame by a transparent resin as positioning the lens with respect to the lead frame. The molding die of the present invention has a positioning pin to support the lens during the molding. Because the lead frame is aligned with the molding die, the precise alignment between the active device on the lead frame and the lens is not spoiled during the molding.

摘要： An optical system 111 collimates wavelength components of wavelengths λ1-λ3 emerging from an end face of optical fiber 11, a diffraction grating 121 separates them by wavelength, and an optical system 112 condenses them. The component of the wavelength λ1 is focused at a focus position by the optical system 112 and diverges after the focus position. Then the component of the wavelength λ1 is collimated by an optical system 113, travels via a diffraction grating 122, and is condensed by an optical system 114 to enter an end face of optical fiber 22. The component of the wavelengths λ2, λ3 condensed by the optical system 112 are reflected by reflecting portions 132, 133 set at their respective focus positions, are collimated by the optical system 112, travel via the diffraction grating 121, and are condensed by the optical system 111 to enter an end face of optical fiber.

摘要： An optical signal processor comprises fiber collimators, a first diffraction grating device, a second diffraction grating device, a first half-wave plate, and a second half-wave plate. Each of the diffraction grating devices is of reflection type having a diffracting surface parallel to a yz plane and a grating direction parallel to a z axis. The diffraction grating device diffracts the light outputted from the fiber collimator after collimation. The diffraction grating device diffracts the light diffracted by the diffraction grating device. The half-wave plates having respective optic axes in directions different from each other by 45 degrees are bonded together and are disposed on an optical path between the diffraction grating devices.
