We have theoretically investigated a Tamm plasmon structure covered by subwavelength grating with quasicrystal symmetry using a finite element method. The possibility to support a number of high-Q hybrid optical eigenstates in such systems was demonstrated. The model structure consists of a GaAs/Al 0.95 Ga 0.05 As Bragg reflector covered with a F 6 subwavelength Fibonacci silver/PMMA coverage. The considered system with a quasicrystalline grating has interesting properties and can be used as light filtering and emission amplifying components of optoelectronic systems.
