    摘要： A wavelength multiplexing device has an emitter capable of independently emitting at least two optical signals for at least two kinds of wavelength, respectively and a transmitter including a plurality of optical waveguides into which the optical signals emitted by the emitter are coupled and which independently transmit the coupled optical signals, respectively. While coupling optical signals with the same wavelength among the optical signals emitted by the emitter into the optical waveguides different from each other, the transmitter couples optical signals with wavelengths different from each other into a same optical waveguide.

    摘要： An optical waveguide includes a first cladding, a second cladding, and a core. The core is embedded in the first cladding so as to be exposed on one principal surface of the first cladding that is opposed to the second cladding. The first cladding and the second cladding are arranged so as to sandwich the core. The core is a product formed by a reaction in which a polymeric material that includes branched polysilane and polysiloxane is subjected to at least one process selected from heating and ultraviolet irradiation. The refractive index of the core is higher than the refractive indices of the first cladding and the second cladding.
