All-dielectric one-dimensional periodic structures for total omnidirectional reflection and partial spontaneous emission control
نویسندگان
چکیده
A remarkable property of one-dimensional alldielectric periodic structures has recently been reported, namely a one-dimensional lattice can totally reflect electromagnetic wave of any polarization at all angles within a prescribed frequency region. Unlike their metallic counterpart, such all-dielectric omnidirectional mirrors are nearly free of loss at optical frequencies. Here we discuss the physics, design criteria and applications of the thin-film all-dielectric omnidirectional mirror. The experimental demonstration of the mirror is presented at optical frequencies. Keywords— Dielectric mirror, photonic crystal, photonic band gap, spontaneous emission control.

Semiclassical Coupled Wave Theory for Bandgap Calculations in Periodically Stratified Dielectric Media
Photonic crystals are artificial low-loss either two-dimensional (2D) or three-dimensional (3D) dielectric structures with a periodic modulation of the refractive index. Due to Bragg reflection, electromagnetic (optical) waves cannot propagate through such structures in certain directions, at certain frequencies. Hence, photonic crystals can exhibit bandgaps (even omnidirectional bandgaps in ce...
متن کاملQuantitative analysis of photon density of states for a realistic superlattice with omnidirectional light propagation.
Omnidirectional light propagation in a realistic superlattice is investigated. This work complements two previous articles [Phys. Rev. E 59, 3624 (1999); 61, 5802 (2000)] that analyzed the cases of transverse electric (TE) and transverse magnetic (TM) polarization modes, respectively, of the dielectric superlattice modeled by means of Dirac delta functions. We present a quantitative analysis of...
متن کاملDipole Emission in Finite Photonic Bandgap Structures: An Exactly Solvable One-Dimensional Model
This paper considers an exact model of atomic spontaneous dipole emission and classical dipole radiation in a finite photonic bandgap (PBG) structure. The full three-dimensional (3-D) or two-dimensional (2-D) problem is reduced to a finite one-dimensional (1-D) model, which then is solved for analytically using algebraic matrix transfer techniques. The results give insight to the electromagneti...

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53.

متن کاملReflectance Properties of Thue-Morse 1-D Dielectric Multilayers
Omnidirectional reflectivity is theoretically investigated in four Thue-Morse (T-M) structures S4, S5, S6 and S7. It is observed that the width of omnidirectional reflection region increases with the order of T-M multilayer i.e. from S4 to S7 generation and multiple photonic band gaps exist for both TE and TM modes due to self-similarity of T-M multilayers. It can also be found that multiple om...
