EVANESCENT FIELD OPTICAL FIBER DEVICES

摘要

The present invention is directed to an evanescent field optical fiber device comprising one or more optical fiber and a support which assures mechanical strength of the optical fiber wherein one or more grooves has been machined in the support and in the coating of the one or more optical fiber in order to gain access to the evanescent field. The invention also extends to the use of a support in the mechanical and chemical removal of coating from an optical fiber and a method of gaining access to the evanescent field of an optical fiber device.
