摘要
A method for the fabrication of a device for the attenuation of a signal carried by a fibre optic in the form of a luminous signal comprises: (a) expansion of the optical core of first and second mono-mode fibres; (b) mounting these fibres opposite each other in a capillary containing a liquid crystal; and (c) polymerisation of the liquid crystal to produce an attenuation element. Independent claims are also included for: (a) an attenuation device incorporating two monomode fibres mounted opposite each other in a capillary containing a liquid crystal; (b) application of the attenuation device for operating a power limiter; (c) application of the attenuation device as a voltage controlled variable attenuator; and (d) an attenuation system using a signal carried by fibre optics incorporating the attenuation device.
