We report the design of nonreciprocal resonant transmission/reflection using a one-dimensional photonic crystal (1DPC) adjacent to the magneto-optical (MO) metal film. The nonreciprocal surface modes are found at the interface between the PC and MO metal within the forbidden band of native PC structure. Breaking time-reversal symmetry using external magnetic field gives rise of such unique nonreciprocal properties. Quantitatively understanding of nonreciprocal resonant optical transmission/reflection behavior is performed using an effective admittance-matching theory. With excitation of the nonreciprocal surface modes, light can transmit and be reflected in one-way. Such design offers promising potential in realizing the optical diode.

“…Photonic crystals are piecewise homogeneous with a period on the scale of the wavelength. SPP waves may be excited directly with light incident on the interface of a metal film and a photonic crystal from either side of the interface [89]. A recent study [90] of a SPP wave at the interface of a metal and a 1 dimensional photonic crystal composed of alternating layers of two dielectric materials shows that such SPP waves have a longer propagation length and exhibit larger dispersion than conventional SPP waves.…”

From the beginning of the 20th century, researchers have been interested in surface electromagnetic waves guided by planar interfaces of dissimilar mediums. Much initial research on surface-plasmon waves and surface-plasmonpolariton waves stemmed from theoretical curiosity, but the development of new experimental techniques propelled commercial exploitation for optical sensors of chemical and biological species. Additional surface waves called Dyakonov waves, Tamm waves, and Dyakonov-Tamm waves have emerged during the last 25 years. Experimental observation of Dyakonov waves was reported only in 2009, but the rapid development of experimental apparatus during the 1990s suggests that theoretical predictions will soon be evaluated experimentally, leading to further development of optical detection systems and optical circuitry.

“…When a distributed Bragg reflector (DBR) [11] and a metal surface are put into contact, resonant optical modes confined within the interface layer between them appear. [12,13] These modes, which are referred to as optical Tamm states by analogy with electronic surface states, present electric field intensity profiles with features that bear some similarities to those of surface plasmons.

profile of these structures is explicitly shown in Figure S1 in the Supporting Information, where the spectral and spatial field intensity distribution along the same DBR on different substrates (aluminum and glass) is shown. At variance with surface plasmons, Tamm states can couple directly to free-space propagating photon modes. Hence, if an emitter is placed in the vicinity of the DBR-metal interface, its emission may be efficiently channeled through far-field radiative modes, a significant enhancement of the emission intensity and control over its directionality being at reach. Experimental verification of this effect has been attained by analyzing ensembles of thin metallic patches or layers deposited onto dielectric multilayers, and the versatility and technological potential of this approach repeatedly demonstrated. [14][15][16][17] In most cases in which emission is channeled through optical Tamm states, the layer of emitters is in direct contact with the inner or outer surface of the metal film, hence favoring nonradiative decay of electrons from the excited states.Herein, we demonstrate a design that optimizes the photoluminescence (PL) intensity radiated by a DBR-metal ensemble embedding a single layer of dyed nanospheres. The nanoemitters, which occupy an area of the order of squared centimeters, are located at a predetermined depth within the last layer of the DBR, the one closer to the metal. We follow a design that results from a theoretical optimization procedure that accounts for the effect of optical Tamm states on the PL quantum yield (QY) and outcoupling efficiency in order to attain the maximum luminous power from the outer surface of the DBR. In this way we demonstrate the possibility of controlling the spectrum, directionality, and dynamics of the emission. Self-standing and flexible DBRs embedding the nanoemitters are used as conformably adaptable light-emitting coatings onto metal surfaces of arbitrary composition and curvature. The versatility of this approach is shown by building spectrally narrow perpendicularly emitting flat surfaces and curved ones from which all the emitted light converges in a well-defined focus. For the wavelength range for which outcoupling is optimized, 50% of the total light emitted from the DBR-metal ensembles is extracted within a narrow cone of numerical aperture (NA = 0.2), which implies a 10-fold extracted power enhancement with respect to a similar layer of emitters embedded in an optically homogeneous matrix. Furthermore, a QY of around 50% is estimated from PL decay rate measurements, which implies a 2-fold enhancement with respect to that observed from a dilute suspension of the same emitting spheres.This study demonstrates a design that maximizes the power radiated into free space from a monolayer of nanoemitters embedded in a flexible distributed Bragg reflector conformably attached to a metal surface. This is achieved by positioning the light source at the precise depth within the multilayer for which optical Tamm states provide enhanced quantum yi...
