The taper may be used to control the reflection on a section of terminated line. The ionisation density in the taper, produced by the optical source and its drive circuit, then control the input reflection of the line. A possible implementation of this may be in a stub loaded line, the impedance that the stub presents to the main transmission line being controlled by the optical excitation. A feature of an optically produced plasma, is that the isolation between RF and control circuits may be made virtually perfect in a very simple fashion.
