摘要： An asymmetric lens wherein lens optical characteristics projected on two planes which are in parallel with a lens optical axis and orthogonally cross each other are mutually different, which lens is characterized by satisfying the following simultaneous equations: (w 2)/(w 1) = (f 2)/(f 1) [2]; (w$(1,3)$2)/(w$(1,3)$1) = (f$(1,3)$2)/(f$(1,3)$1) [3]; (d1) = |(s 1) - (s$(1,3)$1)| [4]; (d2) = |(s 2) - (s$(1,3)$2)| [5]. Since this lens has asymmetry stipulated by the simultaneous equations described above, it can provide ideal optical coupling with low loss between optical waveguides having mutually different waveguide modes, between optical waveguides having mutually dissimilar waveguide shapes, between optical waveguides having astigmatism in their radiation patterns, etc.

摘要： A radar transmits a radio wave whose band is spread by a PN code and receives the radio wave reflected by an object (10) and detects the correlation between the received signal and the delayed PN code to detect the object. A reception unit (18) receives the reflected wave from the object by switching three receiving antennae (16a, 16b, and 16c) whose antenna directions are shifted from each other so that the antenna beam patterns overlap with each other. A correlation detector (19) measures the slide widths while the correlation factor between the received signal and the PN code of each antenna exceeds a threshold and a arithmetic processing unit (12) measures the direction of the object in accordance with the slide widths and the beam pattern characteristics of the antenna.

摘要： A waveguide type photodetector (10) of a wide dynamic range, comprising a detector section (14), an attenuator section (18) and a transparent separator section (20) for electrically isolating the detector section and the attenuator section. The detector section includes an n-type light guide layer (28) and an i-type light absorption layer (30), and paired n- and p-type layers (26 and 32) for optical confinement sandwiching the layers (28 and 30) on a substrate (22), so as to form a double-hereto-structure. The attenuation section has the same layer structure as the detector section with the exception that the light absorption layer is formed by a strained MQW layer, and an electrode (16) for absorption control and an electrode (40) are disposed on the front and back surface of the substrate. The detector section, the light absorption layer of the attenuator section and the waveguide constitute a ridge structure with the optical confinement structure in a vertical direction, and form the confinement structure in the horizontal direction. A reverse bias voltage is applied to the electrodes of the attenuator section to control the degree of absorption of incident light to the attenuator section so that the intensity of light propagated to the detector section may be controlled.
