説明

We studied the supply and removal of oil to and from a thin groove and the consequent insertion loss, aiming at matrix optical waveguide switches that utilize optical reflection and transmission effects at the groove. A robot precisely controlled the position of the removal nozzle and the supply needle by a vision servo. The optimum position for the removal nozzle was at the entrance of the groove to a circular oil pool, and the positioning margin was ±10-15 μm around the optimum position. The on-off ratio of the switching light power at the optimum position was about 30 dB. The removal time was proportional to the kinetic viscosity of the oil, and the optimum height of the removal nozzle was independent of the kinetic viscosity of the oil. An analysis of the insertion loss revealed that the main factor in the loss at the reflection is the tilt of the groove wall.
