Electromagnetically induced transparency in hybrid plasmonic-dielectric system

Abstract: Abstract:We present theoretical and numerical analysis of a plasmonic-dielectric hybrid system for symmetric and asymmetric coupling between silver cut-wire pairs and silicon grating waveguide with periodic grooves. The results show that both couplings can induce electromagnetically-induced transparency (EIT) analogous to the quantum optical phenomenon. The transmission spectrum shows a single transparency window for the symmetric coupling. The strong normal phase dispersion in the vicinity of this transparent… Show more

“…Figure 1(c) shows the transmission spectra when the bus waveguide side-coupled with cavity 1 (red solid line and blue circle line), cavity 2 (green dash line) and cavity 3 (black dash line), respectively. We can find that the thansmission spectra of cavity 1 is a wide-band superradiant state, so cavity 1 can be regarded as a bright mode 21 22 . Conversely, trasmission spectra of cavity 2 and cavity 3 are narrow-band subradiant states, thus, cavity 2 and cavity 3 are dark modes 21 22 .…”

“…On the other hand, the surface plasmon polaritons (SPPs), which are the bound nonradiative surface modes that propagate along the metal-dielectric interfaces, have attracted a lot of research interest due to their novel field confinement down to the subwavelength level [17], [18]. Many plasmonic devices, such as the channel drop filters [19], [20], the ring resonators [21]- [23], and the EIT-like devices [24], [25] have been proposed to reduce the device size. These devices provide the opportunities to design optoelectronic components below the optical diffraction limit and to implement novel applications, including sub-diffraction imaging [26]- [29] and optical spectrum manipulation [30], [31].…”

“…In addition, the EIT-like effect, based on the phase coupling, can be switched by adjusting the incident angle 16, 17 . Herein, we studied the EIT-like effect using bright- and bright-mode resonators 18 . Two types of resonators were fabricated at the top [a cut-wire resonator (CWR)] and the bottom [a ring resonator (RR)] of FR-4 substrate.…”
