Article: Colored image produced with guided-mode resonance filter array.
[show abstract] [hide abstract]
ABSTRACT: A method to reproduce colored images with a guided-mode resonance filter (GMRF) array is presented in this Letter. Because of their excellent characteristics, monochromatic light of the three primary colors with high purity can be achieved by using GMRF structures. Moreover, the primary colors are obtained without changing other GMRF parameters except the period, which could be realized easily with laser direct writing technology. The result shows that a colored image with high resolution and verisimilitude can be reproduced.Optics Letters 12/2011; 36(23):4698-700. · 3.40 Impact Factor -
Article: Type of tunable guided-mode resonance filter based on electro-optic characteristic of polymer-dispersed liquid crystal.
[show abstract] [hide abstract]
ABSTRACT: A narrowband guided-mode resonance filter (GMRF) incorporating polymer-dispersed liquid crystal (PDLC) is designed. Simulating the characteristics of the filter with rigorous coupled-wave analysis, we find that the resonance wavelength of the new kind of GMRF can be tuned from 672.4 to 698.4 nm by varying the refractive index of the PDLC layer with the applied voltage. Furthermore, the resonance wavelengths vary in a linear fashion with respect to the refractive index of the PDLC layer. Therefore, the desired resonance wavelength can be conveniently selected and tuned in a tuning range of 26 nm by using the applied voltage.Optics Letters 04/2010; 35(8):1236-8. · 3.40 Impact Factor -
Article: Compensation of reflectance response deviations of guided-mode resonant filters induced by overetching fabrication.
[show abstract] [hide abstract]
ABSTRACT: Unless the fabrication error control is well treated, it easily causes overetched fabrication errors, which causes the resonant peak value deviation during the fabrication process of guided-mode resonant filters (GMRFs). Hence, the fabrication error control becomes a key point for improving the performance of GMRF. We find that, within the range of the groove depth from 93 to 105 nm, the relationship between the overetched error and the resonant peak value deviation is nearly linear, which means that we can compensate the reflectance response deviation and reduce the resonant peak value deviation by the method of covering the layer film on the GMRF. Simulation results show that the deviation is compensated perfectly by this way.Optics Letters 02/2009; 34(1):70-2. · 3.40 Impact Factor
