The antireflection coating is the critically important technology to obtain high performance of optoelectronic devices. In this paper, a multilayered antireflection coating system on the ferroelectric based was developed. We have designed a broadband antireflection coating on ferroelectric based substrate using a modified minimizing search technique. The design approach consisting of tuning and minimizing operations is effective in refining the antireflective performance and simplifying the design structure of desired solution. It is shown that the maximum wide angular visible spectral reflectance of minimizing search antireflection coating design for a some ferroelectric materials multilayer system is reduced to less than 0.35% with 10-12 layered. In this type of antireflection coating we can regulate the optical properties of the system by external electrical or thermal field and design broadband ultralow reflection coating system for optoelectronic devices.
