Something that is chiral cannot be superposed over its mirror image, no matter how it is shifted (ex. our hands). These two mirror images, called enantiomers, rotate plane-polarized light in opposite directions.Chiral nanostructures have unique materials properties that can be used in many applications. In pharmaceutical research and development, chiral analysis is critical, as one enantiomer may be more effective than the other. Researchers at UC Santa Cruz have developed new ways of performing enantiomeric analyses using the plasmonic circular dichroism absorption qualities of nanostructures. 

Multimode optical fiber was first introduced in astrophotonics applications as “light pipes” to transport light from telescopes to instruments. The integration of multimode optical fiber helped to maximize light collection but offered little control over the propagation modes from the collected light, which affects the quality and speed of light transmission. Single-mode optical fiber used in interferometry proved invaluable for spatial filtering and wavefront correction, providing a stable, reliable, and flexible way to guide light in precision sensing and imaging. Photonic lanterns were conceived in the early 2000s to help bridge a gap between the light-gathering efficiency of multimode optical fiber and the precision of single-mode optical fiber. Photonic lantern devices have reasonably addressed the efficient conversion needs between multimode/ multi-modal and multiple single-mode light paths. However, challenges remain with respect to improving and scaling of photonic lantern devices, including coupling efficiency/losses, bandwidth limitations, and high-order mode (>20) capabilities.
