摘要:
An optical pickup device includes: a light source for emitting light in a first wavelength range; an optical element for transmitting the light; a supporting member for supporting the optical element through an adhesive; a first light blocking member for blocking the light emitted from the light source from entering the adhesive when the optical element guides the emitted light to the optical disc; and a second light blocking member for blocking the light reflected from the optical disc from entering the adhesive when the optical element guides the reflected light to the detector unit. In this optical pickup device, at least one of the first and second light blocking member blocks the light in the first wavelength range and transmits light in a second wavelength range.

The present invention provides an optical device including: a light source; an optical element to be irradiated with light emitted from the light source; and a supporting member for supporting the optical element through a cured product of an adhesive. This cured product of the adhesive contains a thermoplastic elastic material. The present invention also provides an optical device including: a light source; an optical element to be irradiated with light emitted from the light source; and a supporting member for supporting the optical element through a cured product of an adhesive. This cured product of the adhesive has a Young's modulus of at least 1.0E+5 Pa but less than 1.0E+7 Pa in an exponential expression, in a temperature range that the cured product of the adhesive reaches due to heat generation during operation.

A dichroic mirror is a wedge-shaped quadrangular prism whose cross-section is a trapezoid having an upper base d and a lower base d+Δd. The dichroic mirror receives on its top surface parallel light emitted from a collimating lens and reflects, off the top surface, most of the parallel light towards a wavelength plate. Moreover, the dichroic mirror transmits, through the top surface, part of the parallel light to output the part of the parallel light from a bottom surface facing the top surface toward a front monitor. The dichroic mirror has, on the bottom surface thereof, an inclination of an angle φ with respect to the top surface in a direction where a normal vector N of the bottom surface intersects with an xy-plane formed of: an optical axis x of incident light from the collimating lens; and an optical axis y of light emitted towards the wavelength plate.

A light intensity control device of the present invention includes a light source for outputting a plurality of types of light beams having different wavelengths; a light receiving section for receiving and converting the light beams into an electric signal in accordance with the intensity of the respective light beam; and a polarization separation section provided between the light source and the light receiving section. The plurality of types of light beams include a first light beam and a second light beam having a longer wavelength than that of the first light beam. The polarization separation section guides both a first polarization direction light component of the second light beam and a second polarization direction light component, perpendicular to the first polarization direction, of the second light beam to the light receiving section. The polarization separation section guides a first polarization direction light component of the first light beam to the light receiving section, and suppresses a second polarization direction component, perpendicular to the first polarization direction, of the first light beam from advancing to the light receiving section.

摘要:
In a semiconductor substrate of a first conductivity type, first to third drain offset regions of a second conductivity type are formed in that order in a bottom up manner. A body region of the first conductivity type is formed partly in the second drain offset region and partly in the third drain offset region. The second drain offset region has a lower impurity concentration than the first and third drain offset regions. A curvature portion of the body region is located in the second drain offset region.
