The new wave coupling theory of linear electrooptic effect is used to study the thermal property of an electrooptic modulator made from biaxial crystal KTP. We find one direction, along which the output intensity of the modulator is not sensitive to temperature within an angle range of azimuth φ. Furthermore, we achieve an optimal design of the modulator by adjusting the length of the crystal and the direction of the external electric field.
