摘要： A power supply circuit is disclosed in which the influence due to variation in the characteristics of transistors is reduced by variation alleviating devices, each connected to transistors that constitute a current mirror. The power supply circuit comprises a configuration having a current mirror to produce a reference voltage. A multiple number of transistors constitute a current mirror. Multiple variation alleviating devices are connected in series with individual transistors.

摘要： A part of a wavelength division multiplexed optical signal output from a multiplexing area is extracted as a check signal, and then the extracted signal is guided to a multiplexing area. A reentered check signal is detected at a facet located opposite a facet from which the check signal has been reentered, and the state of the detected check signal is determined. Furthermore at need, on the basis of the result of the determination, a control signal is output that controls operations of a plurality of optical signals input to the multiplexing area.
