Abstract: A strobe device of the present invention includes a light source; an optical element; and reflector having reflecting surface. Reflecting surface includes first reflecting surface formed closer to reflector than from specific reflecting region in reflecting surface; and second reflecting surface formed closer to the optical element. Further, first reflecting surface has a shape curved so as to have its center of curvature inside reflector. Second reflecting surface has a shape curved so as to have its center of curvature outside reflector and to be more remote from an optical axis with decreasing distance to the optical element. This prevents light emitted from the light source from illuminating part other than a desired region.

Abstract: To solve problematic trade-off between a bandwidth and a in-band deviation in an optical signal receiving circuit of a gigabit order that is required to have a wide dynamic range, the optical signal receiving circuit has a current-voltage conversion circuit that receives as an input a current signal outputted from a photoelectric conversion circuit for receiving and converting an optical signal into a current signal and converts it into a voltage signal, and realizes the wide dynamic range by providing the current-voltage conversion circuit with an AGC function and a phase compensation function by MOS transistors and a capacitance. Further, by providing the current-voltage conversion circuit with a second phase compensation function by a MOS transistor and a capacitance, it is made possible for the optical signal receiving circuit to reduce the in-band deviation at the time of minimum gain while securing the bandwidth at the time of maximum gain.

Abstract: An optical signal receiving circuit has a current-voltage converting circuit which receives the output current signal of a photoelectric converting circuit, converting an optical signal into the current signal, and converts the current signal into a voltage signal. A differential circuit in the subsequent stage to the current-voltage converting circuit uses a resistor as its current source to facilitate setting of an operating voltage level in the circuit. To eliminate an adverse effect of asymmetry of the output waveform from the differential circuit due to the use of the resistor, the reference voltage level as the other input to the reference circuit is generated from the output voltage signal of the current-voltage converting circuit by a voltage generating circuit incorporating a feed-forward-controlling connection. Thus, coexistence of high bandwidth characteristics and broad dynamic range having so far been difficult to attain by low voltage apparatus can be realized.
