Abstract
Totally six polarization-maintaining optical fibers having the same beat length are arranged at both ends of a single-mode optical fiber and both ends of a single-mode optical fiber coil, respectively. An angle between a principal axis of polarization in a first polarization-maintaining optical fiber and a plane of polarization of linearly polarized light from a light source is 45 degrees. The optical length of each of the six polarization-maintaining optical fibers is larger than a coherent length of the linearly polarized light from the light source. The total of the optical lengths of the six polarization-maintaining optical fibers into which polarization rotation in the process of passing through the single-mode optical fibers is factored is larger than the coherent length of the linearly polarized light from the light source.

Abstract
A power supply device according to the present invention is provided with an input capacitor, a step-down DC/DC converter, a step-down control unit, a power storage capacitor, a step-up DC/DC converter, and a step-up control unit. The step-down DC/DC converter steps down the input voltage of the input capacitor. The step-down control unit initiates the step-down when a first input criterion is met and stops the step-down when a second input criterion is not met. The power storage capacitor has a large capacity and stores the charge output by the step-down DC/DC converter. The step-up DC/DC converter steps up the voltage from the storage voltage to the output voltage and outputs the power. The step-up control unit initiates the step-up when a start criterion is met and stops the step-up when a maintenance criterion is not met. The storage voltage which meets the start criterion is greater than the storage voltage which meets the maintenance criterion.
