    Abstract: A semiconductor optical switch and an optical switch array for use in an optical logic circuit, photonic switching, OEIC, etc., wherein a light amplifying means is provided on a bypass waveguide that connects a plurality of optical waveguides, thereby enabling improvement of the light crosstalk and the light propagation loss. In particular, according to the arrangement of the present invention that a light amplifying means is provided in addition to the deflecting portion, no noise component is amplified and therefore the SN ratio is markedly increased.

    Abstract: A method for producing an optical fiber comprises (i) the step of depositing a barrier layer on the inner wall surface of a glass tube by the CVD (chemical vapor deposition) process, said barrier layer being capable of preventing the diffusion of impurities and being made of high-silica glass which has a refractive index that is substantially equal to that of the glass tube and which contains at least one substance for lowering the refractive index of silica and at least one substance for raising the refractive index of silica, (ii) the step of depositing a glass film of desired refractive index on the barrier layer by the CVD process, (iii) the step of heating and collapsing the resultant glass tube into a composite rod or the so-called optical fiber preform, and (iv) the step of heating and drawing said optical fiber preform into the optical fiber, whereby the optical fiber which has the impurity diffusion-preventing layer between the core and the outside glass layer can be easily produced.
