This numerical study demonstrates the possibility of exciting a chiral optical Tamm state localized at the interface between a cholesteric liquid crystal and a polarization-preserving anisotropic mirror conjugated to a metasurface. The difference of the proposed structure from a fully dielectric one is that the metasurface makes it possible to decrease the number of layers of a polarization-preserving anisotropic mirror by a factor of more than two at the retained Q-factor of the localized state. It is shown that the proposed structure can be used in a vertically emitting laser.

“…TPP resonance can be interrogated by reflection, transmission, absorption spectroscopy, intensity interrogation, or phase measurement [20]. Due to its prominent characteristics, TPP has wide applications in sensing [21], lasing [22,23], perfect absorber [24], solar cell [25], optical filtering [26], and nonlinear optics [27]. In particular, TPP sensing has been demonstrated for detection of temperature [28], pressure [29], surface deformation [30], refractive index (R.I.) [31], organic vapor [32], greenhouse gases [33], liquids [34], fat concentration in milk [35], blood components [36], and theoretically predicted to be suitable for biosensing [37].…”

Tamm Plasmon Polariton (TPP) is a nanophotonic phenomenon that has attracted much attention due to its spatial strong field confinement, ease of mode excitation, and polarization independence. TPP has applications in sensing, storage, lasing, perfect absorber, solar cell, nonlinear optics, and many others. In this work, we demonstrate a biosensing platform based on TPP resonant mode. Both theoretical analyses based on the transfer matrix method and experimental validation through nonspecific detection of liquids of different refractive indices and specific detection of SARS-CoV-2 nucleocapsid protein (N-protein) are presented. Results show that the TPP biosensor has high sensitivity and good specificity. For N-protein detection, the sensitivity can be up to 1.5 nm/(µg/mL), and the limit of detection can reach down to 7 ng/mL with a spectrometer of 0.01 nm resolution in wavelength shift. Both nonspecific detection of R.I. liquids and specific detection of N-protein have been simulated and compared with experimental results to demonstrate consistency. This work paves the way for design, optimization, fabrication, characterization, and performance analysis of TPP based biosensors.

“…The reflectance spectra of the device plotted in Fig.9(f), (g) and (h) reveal the tunability of Tamm mode by varying the angle of incidence to 0 o , 45 o , and 90 o , respectively due to the birefringence property of the LC layer. LC based tunable Tamm plasmon devices are widely demonstrated due to their large birefringence and easy controllability via external stimuli[116][117][118].…”
