A kind of tunable wavelength selective optical switch was proposed for the first time.It is based on Fabry-Perot cavity.The optical switch has two-input and two-output fiber ports.Each fiber carries
N
wavelengths
one or more of which can be selected.The maximum insertion loss is 3 dB and the tunable wavelength range is over 10 nanometers.The tuning mechanism is a sand-wiched multi-layered piezoelectric ceramic.The tunable span can reach 3.3 nm under 5 VDC voltages.The switching time is about 1 ms and the on/off ratio is over 30dB.The optical spectrum of the switch is also studied.At last
some applications of such optical switch are discussed.
