摘要： PROBLEM TO BE SOLVED: To provide a socket which is easily usable for photoelectrical or photoelectric connection by consisting of the connection to an external device of a substrate accompanied by plural optical channels for electromagnetic waves. SOLUTION: Fiber optical face plates 13 transmit the light input and output of the photoelectric device 12. The fiber optical face plates 13 have markers 2111 including grooves and holes. The markers 2111, 2112 are formed not in the fiber optical face plates 13 but on the front surfaces of the fiber optical face plates 13. Parts are mounted in line up with an already treated structure 12 by, for example, adhesives, to the face plates 13. The markers 211 usually include the markers 2111 for position regulation and the characteristic parts 2112 for mounting the external device through plugs. The structure is used together with the inside of the fiber optical face plates 13 or markers 211 on the surfaces as the socket.

摘要： A device for detecting electromagnetic radiation in a semiconductor substrate wherein the electromagnetic radiation being absorbed in said substrate being spatially modulated, said electromagnetic radiation thereby creating a signal with a spatially modulated component in said substrate. Thus, a novel optical detection principle and associated structure is provided for semiconductor substrate detectors in general and for CMOS circuits in particular. Photons absorbed in the neutral zone of the substrate generate electron hole pairs that migrate by diffusion. A shadow mask gives a spatial modulation to the incident, and consequently, to the absorbed radiation. By measuring the magnitude of the spatial frequency component in the minority carrier distribution with spatial frequency corresponding to that of the shadow mask, a fast detector is conceived. A shadow mask with higher spatial modulation frequency delivers a faster turn-off. The combination of a plurality of these detectors with an image fiber forms a basic system for constructing high-speed parallel optical interconnects between chips.

摘要： PROBLEM TO BE SOLVED: To detect single-channel radiation input light at high speed by modulating a radiation light absorbed into a semiconductor substrate spatially to generate a plurality of signals and then detecting the output signal from a detector by comparing the temporal behavior thereof. SOLUTION: Delay detector regions 37-39, shielded with opaque elements (shadow mask) 29-31 and light-transmitting intermediate or direct detector regions 25-27, are formed on a semiconductor substrate of CMOS, or the like. An incident light to the substrate is shielded partially by the opaque elements 29-31 and the density of light-generating carriers is modulated depending on the shadow mask 20-31, such that it is maximized at a time t0 and decreased diffusing with a time t1 -t4 . Consequently, an optical pulse is maximized immediately before time t0 , and the current passing through the intermediate detector regions 25-27 is proportional to the intensity of the optical pulse. On the other hand, the current passing through the regions 37-39 responds to the optical pulse with a potentially and a lag. Consequently, the pulse width of the differential signal becomes extremely shortened, and the radiation input light can be detected at a high speed.
