B. Ortega et al., EXPERIMENTAL DEMONSTRATION OF AN ULTRASELECTIVE AND TUNABLE OPTICAL BANDPASS FILTER USING A FIBER GRATING AND A FABRY-PEROT, Electronics Letters, 33(8), 1997, pp. 669-671
The authors report on the use of a structure composed of a fibre Fabry
-Perot and a fibre grating as an ultraselective and tunable optical ba
ndpass filter. The first experimental demonstration of the filter oper
ation is presented and a range of tuning of several hundreds of gigahe
rtz can be achieved by using the presented techniques.
