TAILIEUCHUNG - Polarization dependence on high-order reflection spectroscopy of artificial opal photonic crystal

We present polarization- and angle-resolved optical reflection of a fine artificial opal photonic crystal consisting of SiO2 spheres into a face-centered-cubic lattice. The measurement shows the polarization dependence on high-order reflection (energy region a/λ = – ). It is shown that the reflection peaks are strongly dependent on s- and p-polarized light illuminating on the sample. The experiment results are analyzed and compared with photonic bands which are obtained according to prediction based on group theory. | Communications in Physics, Vol. 28, No. 3 (2018), pp. 247-254 DOI: POLARIZATION DEPENDENCE ON HIGH-ORDER REFLECTION SPECTROSCOPY OF ARTIFICIAL OPAL PHOTONIC CRYSTAL LE DAC TUYENa,† AND VU DINH LAMb a Department of Physics, Hanoi University of Mining and Geology, 18 Pho Vien, Bac Tu Liem, Hanoi, Vietnam b Institute of Materials Science, Vietnam Academy of Science and Technology, 18 Hoang Quoc Viet, Hanoi, Vietnam † E-mail: ledactuyen@ Received 31 July 2017 Accepted for publication 01 August 2018 Published 31 August 2018 Abstract.

INTRODUCTION The interaction of light with photonic crystals (PhCs) exhibits unique features due to its subwavelength nature of the surface and the periodic variation of refractive index in the depth of the crystals [1–4]. The understanding of optical properties of opal PhCs in the high frequency region is great importance, because it leads to realistic applications. Many exotic optical phenomena offer working mechanisms for optical devices based on photonic band gap [2–4]. Moreover, their novel nontrivial properties can be used to advance in fundamental aspects of the interaction of light and condensed media [2, .
