    • A waveguide type optical device performs such monitoring as detection of a relative position of an insert plate to a groove. The waveguide type optical device comprises a groove disposed at an intersection position of a first optical waveguide and a second optical waveguide; an insert plate disposed to be insertable into the groove; means for applying a static magnetic field such that a vector product of a velocity vector (A) of the insert plate and its magnetic field vector (B) is nonzero; a cantilever that has electrical wiring including therein a wiring part lying in a direction perpendicular to both the velocity vector and the magnetic field vector and that supports the insert plate; and means for detecting a relative position of the insert plate to the groove by detecting a current induced in the electrical wiring.

    • A movable plate 21 is fastened to a substrate 11 via flexure parts 27a and 27b, and can move upward and downward with respect to the substrate 11. The substrate 11 also serves as a fixed electrode. The movable plate 21 has second electrode parts 23a and 23b which can generate an electrostatic force between these electrode parts and the substrate 11 by means of a voltage that is applied across these electrode parts and the substrate 11, and a current path 25 which is disposed in a magnetic field, and which generates a Lorentz force when powered. A mirror 12 which advances into and withdraws from the optical path is disposed on the movable plate 21. When the movable plate 21 is caused to move from the lower position in which the electrostatic force is increased to the upper position, the control part controls the current so that the Lorentz force is generated in a downward orientation and gradually decreases while the movable plate 21 is moving from an intermediate position to the upper position. As a result, the mobility range of the movable part can be expanded without applying a high voltage or sacrificing compact size, and the power consumption can be reduced; furthermore, the reliability in the case of long-term operation can be increased.
    • 可移动板21通过挠曲部件27a和27b固定到基板11上,并且可相对于基板11上下移动。 基板11也用作固定电极。 可移动板21具有第二电极部分23a和23b,其可以通过施加在这些电极部分和基板11上的电压而在这些电极部分和基板11之间产生静电力,以及电流通路25, 被设置在磁场中,并且当通电时产生洛伦兹力。 在可动板21上设置有从光路前进和退出的反射镜12。 当可动板21从静电力增加的下部位置移动到上部位置时,控制部分控制电流,使得向下方向产生洛伦兹力并逐渐减小,而可动板21 从中间位置移动到上位置。 结果,可以在不施加高电压或牺牲紧凑尺寸的情况下扩大可移动部件的移动范围,并且可以降低功耗; 此外,可以增加长期运行情况下的可靠性。
