Casting Light on Counterfeit Products Through Nano-optical Technology

Each year, an estimated two trillion dollars is lost globally due to counterfeit products ranging from jewelry to medicine. As current security labels and product authentication methods are rapidly becoming obsolete or easy to hack, there is a rising urgency for more secure anti- counterfeiting labels.

Review: Recent Progress and Applications of Hyperbolic Metamaterials

Hyperbolic metamaterials (HMMs), which have an extremely high anisotropy with a hyperbolic dispersion relation, are rising as an innovative method of manipulating light. HMMs have received tremendous interest in photonics for their applicability to various fields such as super-resolution imaging, negative refraction, and emission engineering.

Despite all the advances in consumer technology over the past decades, one component has remained frustratingly stagnant: the optical lens. Unlike electronic devices, which have gotten smaller and more efficient over the years, the design and underlying physics of today’s optical lenses haven’t changed much in about 3,000 years.

Despite all the advances in consumer technology over the past decades, one component has remained frustratingly stagnant: the optical lens. Unlike electronic devices, which have gotten smaller and more efficient over the years, the design and underlying physics of today's optical lenses haven't changed much in about 3,000 years.
This challenge has caused a bottleneck in the development of next-generation optical systems such as wearable displays for virtual reality, which require compact, lightweight, and cost-effective components.
