Abstract:
1. An optical-electrical hybrid integrated circuit comprising: an operating unit that includes a first operating block that performs a prescribed operation, a second operating block that performs a prescribed operation, and a standby-state-signal generating unit that generates a standby state signal for switching between a standby state and an operation state of the operating unit; an optical-signal transmitting unit that is connected to the first operating block and the second operating block and converts an electric signal, which is a result of the operation in the first operating block, into an optical signal, transmits the optical signal, converts the transmitted optical signal back into an electric signal, and then applies the electric signal converted from the optical signal to the second operating block; a power supply unit that supplies an electric power to the first operating block, the second operating block, and the standby-state-signal generating unit and the optical-signal transmitting unit; and a power-supply control unit that controls a supply of the electric power to the first operating block, the second operating block, and the standby-state-signal generating unit and a supply of the electric power to the optical-signal transmitting unit, wherein the power-supply control unit controls the supply of the electric power to the optical-signal transmitting unit and the supply of the electric power to the first operating block, the second operating block, and the standby-state-signal generating unit in response to the standby state signal.
