PURPOSE:To realize 1XN optical switches by taking advantage of the characteristic of optical switches formed by using V-grooves that these switches do not require positioning devices and can, therefore, be miniaturized. CONSTITUTION:Substrates 10, 30 having plural pieces of the V-grooves are disposed to face each other. A substrate 70 for aligning is disposed in front of the lower substrate 10 and is provided with the V-grooves 71 to 75. Optical fibers 21 to 25 are previously fixed to these grooves. An optical fiber 40 for switching fitted with a magnetic material 42 is inserted into the arbitrary V- groove of the lower substrate 10 and is held butted against arbitrary one piece of the stationary optical fibers. Both right and left sides of the upper substrate 30 are provided with electromagnets 81, 82. The rear surface of the lower substrate is provided with a permanent magnet 84 and an electromagnet 83 which temporarily eliminates the attraction force of this permanent magnet. The optical fiber 40 for switching is moved to the desired V-groove by proper on and off of the electromagnets 81 to 83 and is made to turn on with one piece of the stationary optical fibers 21 to 25. This state is assured by the permanent magnet 84. |
