J. Capmany et al., FIBER OPTIC BANDPASS FILTER WITH SUBPICOMETRE BANDWIDTH USING A FIBERGRATING AND 2 FIBER FABRY-PEROT FILTERS, Electronics Letters, 33(23), 1997, pp. 1970-1972
The authors present experimental results demonstrating the operation o
f a fibre based optical bandpass filter with subpicometre (0.016pm) FW
HM bandwidth. The filter is composed of a fibre gating and two fiber F
abry-Perot filters in tandem.
