Abstract: An optical semiconductor device outputting a predetermined wavelength of laser light includes a quantum well active layer positioned between a p-type cladding layer and an n-type cladding layer in thickness direction. The optical semiconductor device includes a separate confinement heterostructure layer positioned between the quantum well active layer and the n-type cladding layer. The optical semiconductor device further includes an electric-field-distribution-control layer positioned between the separate confinement heterostructure layer and the n-type cladding layer and configured by at least two semiconductor layers having band gap energy greater than band gap energy of a barrier layer constituting the quantum well active layer. The quantum well active layer is doped with 0.3 to 1×1018/cm3 of n-type impurity.

Abstract: In a transmission path transmitting high-frequency signals each signal contains a frequency component of over 8 GHz. The transmission path includes a nickel-phosphorus layer containing nickel and phosphorus, and a phosphorus concentration of the nickel-phosphorus layer is over 0 mass % and less than 8 mass %. Such a structure enables the transmission path to have little loss even when a signal at a frequency of over 8 GHz is transmitted.
