Regulation Properties Of Liquid Crystal Defect One-dimensional Photonic Crystal Micro-cavity

As the advent of photonic crystal in 1980s,, much research of it in this field by scholars, the theory of photonic crystal has become increasingly deepen and mature. At present the development of photonic crystal to such an extensive situation, mainly because its physical properties and the production of photonic crystal devices have newer features and benefits than traditional optical devices. Photonic crystal is a periodic arrangement of two kinds of high and low refractive index optical materials, which has a unique physical property - photonic band gap. Using this unique advantage of physical property, we can design many optical devices which have new physical properties. In this paper, based on one-dimensional photonic crystals, using liquid crystal as defect, we can constitute liquid crystal defect one-dimensional photonic crystal, and then we discuss the nature of the micro-cavity and effects of temperature and voltage to it.In this paper, from the transfer matrix, simulating one-dimensional photonic crystal the photonic band gap, analyzing the factors that affect the photonic band gap; describing of nematic liquid crystal and its temperature characteristics, mainly around the liquid crystal thermo-optic effect and electro-optic effect, analyzing effects of temperature and voltage on the nematic liquid crystal physical properties, focusing on analysis of the impact of temperature and voltage on the birefringence. After mixing nematic liquid crystal defect in one-dimensional photonic crystal, based on micro-cavity resonance conditions, we design a model of one-dimensional photonic crystal micro-cavity which has nematic liquid crystal defect, and use of transfer matrix to calculate micro-resonant cavity performance parameters, such as resonant wavelength, defect-mode width, quality factor, etc. Using temperature and voltage as variable observations, discuss parameter effect and regulation for micro-resonant cavity.Resonant wavelength represents the center point of resonance phenomenon occurring value. Defect-mode width of micro-resonant cavity is an important parameter and the label generated resonance bandwidth, which directly determines the pros and cons of one-dimensional photonic crystal micro-cavity properties. Similarly, micro-resonant cavity quality factor is also the important parameters. In this paper, Using theoretical calculation and numerical simulation, we make changes in images, to observe the temperature and voltage changes have led to one-dimensional photonic crystal micro-resonator performance parameters change. Finally, according to the temperature and voltage control, synthetically adjust one-dimensional photonic crystal micro-resonators.
