A solid-state imager includes a pixel unit for converting incident light into an electrical signal, a substrate bearing the pixel unit formed thereon, an analog-to-digital converter, formed on the substrate, for converting a signal read from the pixel unit into a digital signal, an optical communication unit, arranged on the bottom surface of the substrate opposite the surface of the substrate bearing opposite the top surface of the substrate bearing the pixel unit receiving the incident light, for converting the digital signal converted by the analog-to-digital converter into a light signal and outputting the light signal, and a signal line for transferring the digital signal, converted by the analog-to-digital converter, to the optical communication unit arranged on the bottom surface of the substrate.

The present invention relates to a coaxial connector and another coaxial connector with an antenna. According to the coaxial connector provided by the invention, one connector is rotated compulsively at an anti-dropping fixing state of a pair of connectors. Therefore the connectors are positioned and fixed with a random angle. The connectors comprise a first connector and a second connector in pair. The first connector comprises the following components: a first core conductor; and a fixing component which accommodates the core conductor. The second connector comprises the following components: a second core conductor which is connected with the first core conductor; a connector housing which accommodates the core connector and is inserted into the fixing component. The fixing component comprises a fixed part and a plurality of fixing fingers. The fixing fingers extend from the fixed part frontward and are respectively provided with a fastening part at the front end. The connector housing comprises a blocking part which is blocked with the fastening part at the inner wall surface and anti-rotation projections for performing rotation prevention of the fixing component. When a random connector is rotated compulsively, the fixing fingers elastically deform and exceed the anti-rotation projections. The connectors are positioned and fixed according to a preset angle.

A disclosed optical element includes three or more sub-wavelength convexo-concave structures having pitches less than a wavelength of an incident light incident to the optical element and having groove depths equal to each other and a periodic structure having the three or more sub-wavelength convexo- concave structures, the pitch of the periodic structure greater than the wavelength of the incident light, in which a predetermined polarization direction of the incident light is diffracted mainly into a specific order.
