摘要： An optical pickup which is configured to suppress resonances in the objective lens which are caused during tilt control of the objective lens is provided. The optical pickup device includes an objective lens, a lens holder for retaining the objective lens, and an actuator for rotating the lens holder to control tilt of the objective lens. The objective lens is bonded to the lens holder via adhesives applied at a plurality of adhesion positions. The adhesion positions at which the objective lens and the lens holder are bonded are asymmetrical relative to a plane which includes the rotation axis of the lens holder and the optical axis of each objective lens.

摘要： A light receiver comprises a Fresnel lens for collecting light signals, and a light receiving element disposed closer to the Fresnel lens than the focal point of the Fresnel lens for receiving the light signals collected by the Fresnel lens. The Fresnel lens comprises a lens surface group having a plurality of lens surfaces, and a back cut surface group having a plurality of back cut surfaces connecting the lens surfaces. The back cut surfaces are inclined with respect to the center axis of the Fresnel lens. Thus, the light receiver has a high light collection efficiency of light signals incident within a certain acceptance angle.

摘要： An optical space transmission module reduces an upper limit of light output based on a safety standard of a laser, reduces light returned to a laser, and is made smaller in size. The optical space transmission module includes a light emitting section which outputs a transmission light, a base section including a reflection section which reflects the transmission light, and a reflection type diffusion section which reflects and converts into a diffused light the reflected light which has been reflected by the reflection section. The reflection section has a function to increase a beam diameter of the transmission light after reflection.

摘要： The present invention provides an optical receiving device, in which a portion of an optical signal is deflected for optical axis detection only when the optical axis is misaligned to thereby achieve a high S/N ratio of a received signal. A condensing section 100 condenses a received optical signal. An optical element 110 includes a transmission region 111 and a deflecting region 112, and receives the optical signal, which has been condensed through the condensing section 100. A signal light receiving section 120 receives the transmitted light, which has been transmitted through the transmission region 111. A detection light receiving section 130 receives deflected light, which has been deflected through the deflecting region 112 and performs a photoelectric conversion on the received light to thereby output a detection intensity signal that indicates an intensity of the deflected light. An optical axis detection section 140 detects an optical axis misalignment based on the detection intensity signal outputted from the detection light receiving section 130 to output an optical axis detection signal. An optical axis adjustment section 150 performs an optical axis adjustment based on the optical axis detection signal.

摘要： In order to improve a transmission speed of multilevel light transmission, increasing the number of light emitting elements is effective. However, in a method in which light outputs from a plurality of light emitting elements are added, because common mode noise contained in the light outputs is added, deterioration in transmission quality caused by the common mode noise prominently arises. Therefore, a difference between two light outputs is previously assigned to data to be transmitted. Specifically, an optical transmitter 102 converts data Dt to multilevel optical signals OSm1 and OSm2 and transmits the converted multilevel optical signals to an optical receiver 103. The optical receiver 103 restores the data Dt which is previously assigned to a difference between electrical signals ESr1 and ESr2 converted from the multilevel optical signals OSm1 and OSm2.
摘要翻译：为了提高多级光传输的传输速度，增加发光元件的数量是有效的。然而，在添加来自多个发光元件的光输出的方法中，由于相加了包含在光输出中的共模噪声，所以显着地出现了由共模噪声引起的传输质量的劣化。因此，两个光输出之间的差异预先分配给要发送的数据。具体地，光发射机102将数据Dt转换为多电平光信号OSm1和OSm2，并将转换的多电平光信号发送到光接收器103.光接收器103恢复先前分配给电信号ESr1和ESr2之间的差的数据Dt 从多级光信号OSm1和OSm2转换。
