“…One of the advantages of THz SPWs on semiconductor surfaces is the active control of the doping level by temperature, optical pump, magnetic field, etc., which is promising in switching and tuning applications. [87][88][89][90][91] Savel'ev et al 92 predicted the existence of terahertz surface waves in layered superconductors below the Josephson plasma frequency ω j , and such waves are called surface Josephson plasma waves (SJPWs). In a semi-infinite sample, SJPWs can propagate along the interface between an external dielectric and a layered superconductor.…”

Terahertz science and technology promise many cutting-edge applications. Terahertz surface plasmonic waves that propagate at metal-dielectric interfaces deliver a potentially effective way to realize integrated terahertz devices and systems. Previous concerns regarding terahertz surface plasmonic waves have been based on their highly delocalized feature. However, recent advances in plasmonics indicate that the confinement of terahertz surface plasmonic waves, as well as their propagating behaviors, can be engineered by designing the surface environments, shapes, structures, materials, etc., enabling a unique and fascinating regime of plasmonic waves. Together with the essential spectral property of terahertz radiation, as well as the increasingly developed materials, microfabrication, and time-domain spectroscopy technologies, devices and systems based on terahertz surface plasmonic waves may pave the way toward highly integrated platforms for multifunctional operation, implementation, and processing of terahertz waves in both fundamental science and practical applications. We present a review on terahertz surface plasmonic waves on various types of supports in a sequence of properties, excitation and detection, and applications. The current research trend and outlook of possible research directions for terahertz surface plasmonic waves are also outlined.

“…We consider doped Indium Antimonide (InSb) slab which has been most widely studied in the context of coupled magneto-plasmon surface polaritons [41,42] and whose material permittivity dispersion has been wellcharacterized experimentally [43][44][45][46]. For the sake of completeness of our study, we extend the known permittivity model in [44][45][46] to the case of an arbitrarily oriented magnetic field in our geometry and obtain the semi-analytic form of permittivity given by e e w w w where m e =9.109 4×10 −31 kg is electron mass.…”

The interplay of spin angular momentum and thermal radiation is a frontier area of interest to nanophotonics as well as topological physics. Here, we show that a thick planar slab of a nonreciprocal material, despite being at thermal equilibrium with its environment, can exhibit nonzero photon spin angular momentum and nonzero radiative heat flux in its vicinity. We identify them as the persistent thermal photon spin and the persistent planar heat current respectively. With a practical example system, we reveal that the fundamental origin of these phenomena is connected to the spinmomentum locking of thermally excited evanescent waves. We also discover spin magnetic moment of surface polaritons that further clarifies these features. We then propose an imaging experiment based on Brownian motion that allows one to witness these surprising features by directly looking at them using a lab microscope. We further demonstrate the universal behavior of these near-field thermal radiation phenomena through a comprehensive analysis of gyroelectric, gyromagnetic and magneto-electric nonreciprocal materials. Together, these results expose a surprisingly little explored research area of thermal spin photonics with prospects for new avenues related to non-Hermitian topological photonics and radiative heat transport.

“…The transmission, polarization, and magnetooptical properties of InSb have been widely investigated in recent years. [31][32][33][34][35][36][37][38][39][40][41][42] For instance, in 2018, Lin et al [36] reported a nonreciprocal THz reflection on the InSb with the transverse magneto-optical effect (i.e., Voigt configuration). This one-way mirror achieves 35 dB isolation with 6.2 dB insertion loss for a certain linearly polarized (LP) state.…”

The lack of low‐loss and high‐efficiency nonreciprocal isolators has become one of the limitations in the development of terahertz (THz) application systems. This work demonstrates that the longitudinally magnetized InSb can achieve one‐way transmission for one photonic spin state but not for linear polarization (LP) state due to the chiral mirror‐symmetry of the two spin states. To solve this issue, a silicon microstructure is fabricated on the InSb substrate to form a magnetoplasmon/dielectric metasurface, where both the time‐reversal and mirror‐reversal symmetric transmission of the two spin states can be broken. In this device, the forward LP state is efficiently transformed into one of the spin states and output with low loss, but the backward wave is forbidden, which achieves the one‐way transmission for the LP incidence with over 30 dB isolation and only 1.7 dB insertion loss. When a THz polarizer is added behind the device to obtain the LP output, the isolation can reach 40 dB, significantly better than the previous reports. This study is significant to understand the nonreciprocal transmission and manipulation mechanism of THz spin states in the magnetized semiconductor and promotes the development of high‐performance THz isolators under the weak magnetic field.
