Interference and Diffraction

Interference is a characteristic phenomenon exhibited by waves. When two electromagnetic waves interact with their peaks and troughs coinciding, a resulting wave with enhanced amplitude is produced. This is known as constructive interference. In this case, the two waves interacting are in phase with each other.

Background:

Spontaneous emission near plasmonic nanostructures involves complex multipolar pathways beyond simple dipole emission.
Two-photon spontaneous emission (TPSE) exhibits higher-order multipolar emission channels that can interfere.
Understanding these interference effects is crucial for controlling light-matter interactions at the nanoscale.

Purpose of the Study:

To develop a novel computational framework for analyzing interference effects in TPSE near arbitrary nanostructures.
To investigate the breakdown of dipolar selection rules in TPSE due to enhanced multipolar transitions.
To provide a tool for designing quantum emitters and nanostructures for tailored TPSE.

Main Methods:

Developed a framework based on calculating Purcell factors using conventional electromagnetic simulations.
Avoided complex analytical calculations by leveraging established simulation techniques.
Applied the framework to a hydrogen-like emitter near a graphene nanotriangle.

Main Results:

Demonstrated a breakdown of the dipolar selection rule in TPSE near a graphene nanotriangle.
Observed significant enhancement of two-electric dipole (2ED) and two-electric quadrupole (2EQ) transitions.
Quantified the impact of interference between multipolar transitions, showing an increase in the total emission rate.

Conclusions:

The developed framework accurately computes interference effects in TPSE near nanostructures.
Multipolar transitions and their interference play a significant role in TPSE, challenging dipolar selection rules.
Exploiting these interference effects offers a new degree of freedom for enhancing or suppressing specific TPSE pathways.
