| Abstract: | 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 sandwiched multi-layered piezoelectric ceramic.The tunable span can reach 3.3 nm under 5 V DC 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. |
