We have theoretically and experimentally proven the potential of multi-junction VCSELs to achieve high electro-optical conversion efficiency, providing insights for the further development and application of high efficiency semiconductor lasers.

Silver telluride quantum dots are employed in shortwave-infrared photodetectors and in monolithically integrated imagers that are free from toxic heavy metals and fully solution processable.

Phosphor efficiency can be improved via materials development or structural engineering, the latter only begun lately. Here the authors propose and investigate simple vertical resonant cavity as a platform for nanostructurally engineered phosphor.

The strong birefringence of liquid crystalline nanospheres in the body of the Pacific cleaner shrimp enables brilliant whiteness by overcoming undesirable optical crowding effects.

Two-dimensional photonic crystal phosphor is upgraded in terms of both material and structure, which results in ~7 times enhanced color conversion efficiency compared with reference phosphor.

At the 24th General Congress of the International Commission for Optics in Tokyo, photonics-based sensing and simulations were shown to benefit research into phenomena that span the nanometre to astronomical range.
