Abstract
Photonic crystals are engineered structures able to control the propagation and properties of light. Due to this ability, they can be fashioned into optical components for advanced light manipulation and sensing. For these applications, a particularly interesting case study is the gyroid srs-network, a three-dimensional periodic network with both cubic symmetry and chirality. In this work we present the fabrication and characterization of three-dimensional cubically symmetric 8-srs photonic crystals derived from combination of eight individual gyroid srs-networks. We numerically and experimentally investigate optical properties of these photonic crystals and study in particular, the impact of cubic symmetry on transmission and optical activity (OA). Gyroid photonic crystals fabricated in this work can lead to the development of smaller, cheaper, and more efficient optical components with functionalities that go beyond the concept of lenses.
Highlights
Light can be used to collect environmental parameters and provide information about the material that it passes through
The impact of GD-directthe laser writing (DLW) on symmetry and resolution of Photonic crystals (PhCs) can be seen in Figure 3, which shows
To clearly visualize effects of galvo-dithered direct laser writing (GD-DLW) we considered 2-srs networks, a structure with a simple geometry compared to 8-srs networks
Summary
Light can be used to collect environmental parameters and provide information about the material that it passes through. In order to use the information that light can collect, it is essential to develop optical devices and sensors that are able to interact with optical degrees of freedom [2]. Systems that implement machine learning and artificial intelligence make large use of optical sensors and require new solutions to provide new functionalities and improved performance. To harvest their full potential, optical sensors need to become smaller, cheaper, and more efficient. They need to cover a wide range of wavelengths and incorporate new functionalities
