Abstract: Shields that transmit light to be detected and have conductivity are disposed on light receiving surfaces of photodiodes (1 and 2) to prevent electric charges from being induced to the photodiodes (1 and 2) by electromagnetic waves entered from an external. Two kinds of filters having light transmittance depending on a wavelength of light are disposed on the light receiving surfaces of the photodiodes (1 and 2), respectively, to take a difference between their spectral characteristics. The shield and filter may be made of, for example, polysilicon or a semiconductor thin film of a given conductivity type, and may be readily manufactured by incorporating those manufacturing processes into a semiconductor manufacturing process.

Abstract: A photoelectric converter comprising a resin layer that absorbs infrared light cuts out unnecessary infrared light, while the photoelectric converter has a problem that the resin layer also reduces the transmission of light in the visible range. A photoelectric converter improving the problem comprises a semiconductor substrate (2) on which photoelectric conversion elements are formed, a color filter (8) provided on the semiconductor substrate (2), and a support base (21) bonded to the color filter (8), wherein an interference filter (11) comprised of multiple thin layers of dielectric material laminated together and reflecting infrared light is provided to the support base (21). As a result, light attenuation can be minimized while infrared light is cut, and the usage efficiency of light can be increased. A photoelectric converter adjusted to the luminous efficiency of the human eye can be obtained by adjusting the light transmittance characteristics of the color filter (8) to the luminous efficiency of the human eye.

Abstract: An optical receiver, small and inexpensive, is used for a WDM transmission system in place of a wavelength demultiplexer. In the receiver, a light-transmitting medium and a photodiode (PD) are placed on the same substrate, a wavelength-selecting filter is attached perpendicularly or obliquely to the end face of or to a cut section at the midpoint of the medium, the filter transmits only the assigned wavelength included in the incident light having multiplexed wavelengths, and the PD detects only the assigned wavelength. With an optical fiber, the fiber can be housed in a ferrule. In this case, the filter is inserted into a filter-supporting hole provided at a midpoint of the ferrule, the ferrule is fixed in a groove formed on the substrate, and an optical pathway-changing groove formed on the substrate reflects light having emerged from the optical fiber to introduce it into the PD.
