Scaling challenges of metasurfaces

Greg Blackman explores the optical design approaches for modelling metasurfaces

Illustration of a three-dimensional crystal with various types of confining centres. (a) Crystal with four confining centres, each trapping waves (yellow) in all three dimensions simultaneously. (b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)

Researchers further understanding of wave behaviour in photonic crystals

Newly discovered fundamental rules have been embedded into software to dramatically optimise the design of photonic integrated circuits, Matthew Dale finds

The technology for optical systems generation is becoming increasingly diversified, while each stage of the fabrication chain is becoming deeper and more specialised. (Image: PanDao)

Optical Modeling of UV Sterilization Systems

This article is brought to you by: 

Current worldwide conditions have brought a renewed focus on ultraviolet or UV based sterilization systems. UV light has been shown to kill many types of pathogens. A key metric is the dose, or amount of UV light on a surface, as a minimum dosage level is required for effective sterilization. Using optical analysis software as part of the design process ensures that these minimum dosage levels are obtained.

Modeling biological tissues in lighttools

This article is brought to you by: 

This paper presents the most up to date compilation of research and data available in the literature regarding the optical properties of human tissue. The relevant optical, biological, and measurement details are presented to illustrate the necessary considerations that should be observed when modeling human tissue in LightTools. It also describes how this information has been incorporated into a new Human Tissue Utility. This utility aims to take some of the guesswork out of creating User Materials that model biological tissues.
