“…Due to large dielectric contrast between the organic and inorganic [MX 6 ] 4+ octahedral layers, electrons and holes are strongly confined into the octahedral layers and bound together via the Coulombic force. The strongly bound electron–hole pairs suggests a binding energy of several hundred meV, which promises strong light–matter interactions and related applications, such as low‐threshold polariton lasing …”

www.advancedsciencenews.com www.small-methods.com an inorganic or organic cation (Cs + , CH 3 NH 3 + , NH 2 CHNH 2 + , etc.), M is a divalent metallic cation (Pb 2+ , Sn 2+ , Mn 2+ , Fe 2+ , etc.), and X is halogen anion (I − , Br − , Cl − ). [28][29][30] Since 2009, perovskites have gained worldwide attention due to their unprecedented success in photovoltaics. [31][32][33][34][35][36] The power conversion of solution-processed CH 3 NH 3 PbX 3 (MAPbX 3 ) perovskite solar cells has increased from 3.8% to 22.1% within a few years. [37][38][39][40][41][42] Although there is still some debate, it is widely accepted that the high power conversion efficiency of MAPbX 3 is attributed to the high absorption coefficient (≈10 4 cm −1 ), balanced and long diffusion length (≈100 nm to 100 µm), low density of defect states (10 9 -10 10 cm −3 ) and bipolar carrier-transport property. [31,33,34] As a direct-bandgap semiconductor, perovskites also show wide-band tunable emission color and high quantum yield, holding important potential applications in light sources, for example. [40,[43][44][45] Prior to the rapidly developing studies in solar cells, perovskites have been studied as light-emittingdiode (LED) devices for a long time. [46][47][48] In particular, recent studies on photophysical properties, structure engineering, and device development have led to the rapid progress of coherent and incoherent perovskite photonic sources. [44,[49][50][51][52][53][54][55] For example, several groups have demonstrated perovskite LEDs with external quantum efficiency of ≈8-12% using solutionprocessed and thermally evaporated quasi-two-dimensional perovskite thin films, etc. [44,51] Furthermore, perovskite nanostructures including NWs, NPs, and quantum dots (QDs) are also attracting more and more attention for exploring nanophotonic and quantum devices, including single-photon sources, optical detectors, transistors, optical sensors, etc. [56][57][58][59] In a nutshell, despite the Pb toxicity and poor stability, perovskites have been attracting more and more attention in divergent research areas. These fundamental studies on and applications of perovskite photonic sources could extensively push forward our present energy and communication technology.With high absorption coefficient and low density of defects, perovskites are excellent gain materials for the development of high-performance lasing devices. More interestingly, thanks to the long-distance ambipolar carrier-transport properties, perovskites could greatly raise the possibility of realizing electrically driven microlasers and nanolasers. In 2014, Xing et al. demonstrated the first amplification of spontaneous emission (ASE) of CH 3 NH 3 PbX 3 perovskite thin film, which had been solution processed at low temperature. [60] Through embedding CH 3 NH 3 PbI 3−x Cl x perovskite thin films into a distributed Bragg reflector Fabry-Pérot (F-P) cavity, Deschler et al. demonstrated room-temperature perovskite lasing. [49] Beyond these thin films, perovskite nanostructures including NP...

“…The inorganic layers are held together by weak van der Waals forces and can be considered as natural quantum‐well structures, while the semiconducting inorganic layers act as “wells” and the insulating organic layer as “barriers.” Given the very different dielectric constants of the “well” and “barrier,” 2D layered perovskites possess very large binding energies as high as several hundreds of meV, due to enhanced electron–hole interactions along with the decrease of the dimensionality . This strong confinement in 2D structure and wide compositional flexibility show that these layered perovskites are ideal for LEDs and strong light–matter interaction applications, such as low‐threshold polariton lasers …”

Halide perovskites have shown great potential in optoelectronic applications, such as a record photovoltaic efficiency of 23.3%, and an achievement of external quantum efficiency beyond 20% in perovskite light‐emitting diodes, as well as other promising demonstrations of light‐emitting transistors and photodetectors. Moreover, the extraordinary optoelectronic properties of optical absorption, high photoluminescence quantum yield, low non‐radiative recombination rates, large and balanced charge‐carrier mobilities, and high gain coefficients extend their applications into the coherent light sources (laser) field. However, although halide perovskites have made great progress, the realization of solid‐state electrically pumped lasers has not been achieved yet. This review starts with a discussion of the structure, optical properties, and gain behaviors of various perovskite materials. Then, the rapid advances of perovskite‐based laser applications are reviewed, in which they are mainly classified into three sections: optically pumping lasers, strong‐coupling lasers, and continuous‐wave pumped lasers. Finally, the conclusions and some remaining challenges for perovskite electrically driven lasers are highlighted.

“…Some progress in coupling the fundamental optical excitations in semiconductors with SPPs has been achieved, e.g. modifications of the exciton energy spectrum [22,23] and recombination dynamics [24,25] in direct band gap III-V compounds were reported. However, ultrafast studies with optical pulses, which deserve special attention in connection with active plasmonics, have been limited to a few works where the propagation constant of SPPs is controlled due to the modulation of the dielectric function by photoexcited carriers in a semiconductor layer [4,6].…”

Terahertz dynamics of lattice vibrations in Au/CdTe plasmonic crystals: Photoinduced segregation of Te and enhancement of optical response

et al. 2016

Excitation of coherent optical phonons in solids provides a pathway for ultrafast modulation of light on a sub-ps timescale. Here, we report on efficient 3.6 THz modulation of light reflected from hybrid metal/semiconductor plasmonic crystals caused by lattice vibrations in a few nm thick layer of elemental tellurium. We observe that surface plasmon polaritons contribute significantly to photoinduced formation of this thin layer at the interface between a telluride-based II-VI semiconductor, such as (Cd,Mg)Te or (Cd,Mn)Te, and a one-dimensional gold grating. The change in interface composition is monitored via the excitation and detection of coherent optical tellurium phonons of A1 symmetry by femtosecond laser pulses in a pump-probe experiment. The patterning of a plasmonic grating onto the semiconductor enhances the transient signal which originates from the interface region. This allows monitoring the layer formation and observing the shift of the phonon frequency caused by confinement of the lattice vibrations in the nm-thick segregated layer. Efficient excitation and detection of coherent optical phonons by means of surface plasmon polaritons are evidenced by the dependence of the signal strength on polarization of pump and probe pulses and its spectral distribution.
