Resonantly Enhanced Emission from a Luminescent Nanostructured Waveguide

Area of Science:

• Photonics and Optical Engineering
• Materials Science

Background:

• Controlling photon emission is crucial for fundamental science and technology.
• Existing methods use microcavities, photonic crystals, and plasmonic nanocavities to modify photonic states.
• These approaches aim to control spontaneous emission through resonant structures.

Purpose of the Study:

• To demonstrate a novel method for resonantly enhanced light emission.
• To introduce the luminescent nanostructured waveguide resonance (LUNAR) concept.
• To show that emission enhancement can be controlled by design parameters.

Main Methods:

• Coupling emitters in a luminescent waveguide to a resonant waveguide mode.
• Utilizing a periodic nanostructure to outcouple light via diffraction.
• Analyzing the relationship between design parameters and emission enhancement.

Main Results:

• Demonstrated resonantly enhanced emission using the LUNAR concept.
• Showed that emission enhancement is controllable by tuning design parameters.
• Attributed enhanced emission to accelerated spontaneous emission and increased local density of photonic states.

Conclusions:

• Nanostructured luminescent materials can be engineered for functional and enhanced emission.
• The LUNAR concept offers a pathway to improve photonic and optical applications.
• Potential applications include sensors, lighting, displays, and projectors.
