摘要： A low-profile optical disk device which performs recording and reproducing using a plurality of laser light sources with different wavelengths, without thug need for additional components. It is used as a DVD-Ram, CD-R or the like. It comprises a plurality of neighboring laser light sources with different wavelengths: a beam-shaping prism for expanding the width of laser beams in a direction in which the plural laser light sources are arranged; and a focus lens which forms an optical spot on an optical disk, where laser light sources with longer wavelengths are positioned closer to an extension line of a refracted beam created by the beam-shaping prism. The above arrangement enables correction of optical spot coma aberrations caused by a laser light source positioned out of the optical axis of the focus lens, thereby realizing a low-profile optical disk device with high optical performance.

摘要： Concerning an all-optical switch which makes use of a nonlinear change of a refractive index of a nonlinear waveguide caused by absorption of a control light, a method that an electrostatic field is applied to the nonlinear waveguide is known as an effective one for shortening a lifetime of the carrier which obstructs an improvement of a repetition frequency of a switching operation. The semiconductor nonlinear waveguide is constituted of a pin-structure which comprises a nondoped InGaAsP optical waveguide, an under cladding layer formed of a N-type InP substrate and an upper cladding layer formed of a p-type InP layer and etc. Moreover, the under and upper cladding layers are electrically shortcircuited via upper and lower electrodes. Since a builtin voltage caused by a difference in Fermi level between n and p-type cladding layers is applied to a InGaAsP optical waveguide, and electrostatic field can be applied to the optical waveguide of the pin structure to some extent without using a constant-voltage power supply. By application of the aforementioned electrostatic field, the effective lifetime of the carrier is shortened, and a repetition frequency of an switching operation of the all-optical switch can be improved.
