Abstract
We have theoretically investigated Tamm plasmon structure covered by a quasicrystal symmetry subwavelength grating. We show that such structures can support plenty of high-Q hybrid optical eigenstates. The structure consists of a GaAs/Al0.95Ga0.05As Bragg reflector covered with a subwavelength Fibonacci silver/resist sequence. For the F5 type coverage, two different operation regimes controlled by filling factor value were shown. We demonstrate the anti-crossing behaviour of these states spectral position. The considered system can be useful to enhance the emission of broadband light-emitting materials such as organic dyes and small molecules.
