Photomechanical Effects in Polymer Optical Fibers

摘要

Motivated by the well known observation in intensity dependent refractive indexmeasurements that refractive index changes are often accompanied by density and length changes, we have demonstrated photomechanical effects in polymer optical fibers and have investigated the possibility of making all-optical devices that have a mechanical function. We report on the demonstration of two separate devices: An all-optical position stabilizer and digital positioner; and an ultrafast all-optical positioner. jg p. 2.
