The aim is to develop a silicon-silver bilayer hybrid grating to enhance fluorescence and direct emission from dipoles.
Proposed a silicon-silver bilayer hybrid grating with tunable parameters.
Evaluated the performance for fluorescence enhancement and directional emission.
Analyzed the effects of dipole orientations on emission characteristics.
Demonstrated significant fluorescence enhancement across different orientations.
Achieved directional emission for arbitrarily oriented dipoles.
Validated the tunability of enhancement through parameter adjustments.
Abstract
A silicon–silver bilayer hybrid grating with independently tunable parameters is proposed to achieve robust fluorescence enhancement and directional emission for arbitrarily oriented dipoles.
