Based on the characteristics of liquid crystal rafractive index on electric and temperature, electric field and temperature controlled characteristics of defect mode were investigated in one dimensional liquid-crystal-filled photonic crystal with a defect layer by means of transfer matrix method. The results showed that, as the temperature T is in the range from 273 K to 330 K, the wavelength of defect mode shifted to short wavelength and its variation increased with increasing of the angle θ between perpendicular incident light and electric field direction, which is in the range from 0 to π/2, and the maximum controllable value of wavelength is 37.3 nm. As θ is in the range of 0 ～π/2, the wavelength of defect mode will drift, the quantity of the drift is negative at first, and then positive with rising of external temperature T which is in the range from 273 K to 330 K and the maximum controllable value of wavelength is 21.9 nm. When θ is equal to 0.7505, no matter how to change the external temperature T which is in the range from 273 K to 330 K, the defect mode wavelength remains stable. The effect of temperature on the defect mode wavelength is weaker than that of θ between perpendicular incident light and electric field direction on it.
