The electric controlled optical tunable filter of the FP resonant cavity as a micro opto electro mechanical system (MOEMS) device based on silicon is introduced. It is fabricated using silicon micro machined technology. Its basic operation principle is that one of the two mirrors is made into an elastic membrane structure, then the cavity length is varied under the driving of the electric field force, and the wavelength tuning can be realized. According the specifications of our design of the devices, the crosstalk introduced by FP filter in DWDM system is analyzed and the influence of laser bandwidth,filter bandwidth,channel space on crosstalk is discussed. When the channel space is 100 GHz and the laser bandwidth is 5 THz,the crosstalk is -21 dB.
