Semi-analytic modeling of chiral metasurface stacks

2019 Conference on Lasers and Electro-Optics (CLEO), 2019

We analyze the polarization response of a fabricated twisted nano-wire meta- surface stack using a semi-analytic algorithm. This lifts the requirement for rigorous simulations when designing metasurface stacks with specific target functionalities.


Optical metamaterials made by polymer self-assembly

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017

Summary form only given. Optical metamaterials require the manufacture of periodically repeating motives at length-scales that are smaller than the wavelengths they are intended to manipulate. For visible light, this entails the fabrication of 3D design materials with sub-100 nm periodicities. Since this is difficult to achieve using top-down methodologies, bottom-up self- assembly is an interesting alternative approach. The perhaps ...


Linear and Circular Dichroism in Gyroid Optical Metamaterials

A particularly interesting morphology is the gyroid due to its chiral, cubic, and triply-periodic geometry. Gyroid optical metamaterials with unit cell sizes of tens of nanometers can be conveniently fabricated via electrodeposition of gold into voided, self-assembled polymer templates.

  • Optical metamaterials made by polymer self-assembly

    Summary form only given. Optical metamaterials require the manufacture of periodically repeating motives at length-scales that are smaller than the wavelengths they are intended to manipulate. For visible light, this entails the fabrication of 3D design materials with sub-100 nm periodicities. Since this is difficult to achieve using top-down methodologies, bottom-up self- assembly is an interesting alternative approach. The perhaps simplest implementation of self-assembly for metamaterials is the use of block- copolymers replicated into a plasmonic metal. Following Pendry's prediction of negative refraction arising from structurally chiral morphologies [1], self- assembled structures with chiral symmetries are particularly interesting [2]. We have demonstrated that the gyroid (Fig. 1a) is such a candidate morphology [3]. Despite initial successes in the manufacture of gyroidal optical metamaterials [3-6], substantial challenges remain, particularly concerning the control of the control of the self-assembly process and the understanding of light in-coupling and mode-propagation in these interconnected network morphologies. This presentation gives an overview over recent progress in the manufacture of optical metamaterials based on self-assembly and discusses the obstacles in the way of fabricating a structural material that has a negative refractive index in the visible spectral range.

  • Linear and Circular Dichroism in Gyroid Optical Metamaterials

    Optical metamaterials offer the possibility of accessing extraordinary optical properties through the specific arrangement of their sub-wavelength structural units. A particularly interesting morphology is the gyroid due to its chiral, cubic, and triply-periodic geometry. Gyroid optical metamaterials with unit cell sizes of tens of nanometers can be conveniently fabricated via electrodeposition of gold into voided, self-assembled polymer templates. This bottom-up self-assembly approach allows the fabrication of gold gyroids with different orientations and unit cell sizes. We show here that gyroid metamaterials exhibit a depressed effective plasma frequency, as well as a circular and linear dichroism, a surprising result given the underlying cubic symmetry. By combining electron microscopy and optical goniometry, we show that the reflection of light from gold gyroids is strongly polarization- dependent, and is sensitive to the orientation of the gyroid and the terminations of its top surface. Our results highlight the influence of orientation and surface terminations on the optical properties of metamaterials, and have significant consequences for both their design and applications.

  • Coherent absorption of two-photon states in metamaterials

    Multiple photon absorption processes typically have a nonlinear dependence on the amplitude of the incident optical field. On the other hand, quantum technologies rely on single photon events. It has therefore been of great technical difficulty to achieve nonlinear devices using single photons. This is due to the small cross-section of absorption in room temperature devices, with multi-photon absorption events occurring with extremely low probability. The lack of access to nonlinear processes severely inhibits the use of optics for a large number of applications surrounding quantum technologies. We demonstrate experimentally that by exploiting a coherent absorption mechanism for N=2 N00N states, outlined theoretically by Jeffers in 2000 [1] and experimentally explored by Roger et. al. in 2016 [2], that it is possible to determine and enhance the number of two photon states that are absorbed. Here a 50% absorbing metasurface is placed inside a Sagnac interferometer into which we inject a N00N state. We show that by tuning the phase φ of the input state, |2,0〉 + exp(-ί2φ) |0,2〉, we can selectively tune the output state. For an input phase of φ = π/2 or 3π/2 we find that a single photon is absorbed with 100% probability. However, when we tune the input phase to φ = 0 or π we see that either 0 or 2 photons are absorbed with equal probability. We have developed a theoretical model that, with no free parameters, fits the experimentally measured two-photon contribution and finds the maximum contribution of |0,0) (0,0| to the output state to be 40.5%.

  • A square helical metamaterial for broadband circularly-polarized absorber applications

    A metamaterial structure is proposed for using as a broadband circularly polarized absorber, which consists of four metallic square-shaped helices and each helix is opposite-handedness to the adjacent ones. Besides, the electromagnetic wave flows along the helical axes and the proposed structure blocks the circular polarization wave with the same handedness as the helices. The calculated results show that the proposed structure is broadband and independent to polarization.

  • Generation of electromagnetic doughnuts

    Summary form only given. We propose from the first time a practical way of generating flying electromagnetic doughnuts, ultra-short electromagnetic pulses that are exact solutions to Maxwell's equations, distinguished by a doughnut-like configuration of electric and magnetic fields, strong longitudinal field components along the propagation direction, and unique spatiotemporal coupling [1, 2]. Flying doughnuts (FDs) are single-cycle, wide bandwidth pulses that propagate in free-space at the speed of light. In contrast to conventional families of pulses, the spatial and temporal dependence of the FD pulse cannot be separated. FD pulses interact with matter in unique ways, including non-trivial field transformations upon reflection from interfaces and the excitation of strong toroidal response in dielectric particles [3]. Here we introduce a scheme for the generation of FDs based on spatially gradient and frequency dispersive metamaterial arrays. We employ a cylindrically symmetric metamaterial array (see schematic in Fig. 1a), which reflects the axial symmetry of the FD pulse. The spatio-temporal coupling is achieved by varying the scattering properties of the metamaterial elements across the array according to the parameters of the targeted FD pulse: the effective wavelength, q1, and Rayleigh length, q2 [2]. We consider illumination of the metamaterial array by a transverse, short, Gaussian pulse and calculate numerically the scattered electromagnetic fields. Similarly to ideal FD pulses, the generated pulse is of single-cycle nature and toroidal topology, as indicated by the electric field intensity profile of Fig. 1b. Importantly, it exhibits coupled spatial and temporal structure, with a spatially varying frequency spectrum (see dashed green lines in Fig. 1c).
