“…By contrast, TM mode usually possesses a large effective index thus a lower lasing threshold is anticipated. The lasing cutoff thickness for all‐inorganic CsPbX 3 perovskite at room temperature is ≈70 nm and it can be pushed to ≈40 nm at a lower temperature (≈77 K) . While the cut‐off thickness for the fundamental TE and TM modes of MAPbBr 3 are calculated as 28 and 63 nm, respectively.…”

“…But when the film thickness approaches the cut‐off thickness, there is a large TE‐mode leakage into the substrate . According to the investigation on conventional MAPbX 3 ‐Au hybrid plasmonic nanolasers (Figure d,e) . When the thickness of the perovskite microplate is large, both the TM‐polarized photonic mode and the hybrid plasmonic mode can propagate inside the hybrid waveguide.…”

Lead halide perovskites are considered as very promising photovoltaic materials due to their tunable direct bandgaps, large absorption coefficients, long carrier diffusion lengths, and ultralow trap state densities, etc. With these unique properties, the lead halide perovskites have also demonstrated great potential for use as semiconductor gain materials. In this review, a snapshot on the recent advances of lead halide perovskite micro‐ and nanolasers is given. The dependence of lasing performance on the perovskite dimensionality, crystal size, and operation temperature is systematically discussed. Furthermore, the development of continuous wave (cw) pumped perovskite lasers and lead‐free perovskite lasers is also summarized. In the final section, the challenges and future prospects of metal halide perovskite lasers are provided. These pieces of knowledge would help advancing the development of perovskite on‐chip coherent light sources.

Over the past decades, many materials and techniques have been successfully developed for UV and deep-UV lasers, e.g., III-Nitrides semiconductors and nonlinear optical materials. But their practical applications in biomedical diagnostics and phototherapy are usually hindered by either the difficulty in shifting the emitting wavelengths into UVB regime or their dependence on extremely high pumping flux and device sizes. Recently, lanthanide (Ln 3+ )-doped upconversion nanocrystals (UCNCs) have been an ideal class of candidates for miniaturized UV lasers. [5] Such kind of materials can be simply synthesized from solution-processed approach with unique biosafety feature. [5,6] Most importantly, their ample electronic configurations make Ln 3+ ions ideal for high-order photon upconversion. [7][8][9][10][11] In past few years, UV emissions from Pr 3+ , Yb 3+ -Tm 3+ , and Yb 3+ -Er 3+ -Tm 3+ systems were established for photodynamic therapy treatment, optical memory, and water splitting applications. [7][8][9] Particularly, exceptional vacuum ultraviolet (i.e., 195.5 nm) upconversion emission was realized from Yb 3+ -Tm 3+ -Gd 3+ codoped fluoride nanocrystals under excitation of a 980 nm laser diode. [10] Likewise, the deep-UV-to-blue emission was achieved from Er 3+ -doped BaGd 2 ZnO 5 powders pumped by a visible light-emitting diode. [11] Despite the above exciting achievements, Ln 3+ -based on-chip UVB lasing emission (i.e., <280 nm) still remains a daunting challenge. On one hand, it is quite difficult to achieve an intense emission in UVB spectral region. While a high doping concentration of Ln 3+ can significantly enhance upconversion intensity, [12][13][14] the nonradiative quenching, [15] which comes from the concentration quenching and surface quenching effects, poses a significant limitation on the realization of sufficient UVB upconversion gain. Recent achievements in the construction of multilayer structure [16,17] have shown their potential in alleviating the appreciable quenching by surface passivation and suppressing long-distance energy migration, thus increasing the doping content. However, the decreasing lifetime of Yb 3+ ions along with the increasing Yb 3+ content [13] and the competitive emissions that consume the same energy pool obviously lead to the depletion of excitation energy. As a result, there is still an obvious lack of Ln 3+ -doped UCNCs with robust UVB upconverting stimulated emission. On the other hand, the absence of an appropriate chip-scale laser cavity hampers the utilization of miniaturized UVB lasers. Due to the constraints of strain Lanthanide (Ln 3+ )-based ultraviolet B (UVB) microlasers are highly desirable for diagnostics and phototherapy. Despite their progress, the potential applications of UVB microlasers are strongly hindered by their low optical gain, weak light confinements, and poor device repeatability. Herein, a novel allin-one approach to solve the above limitations and realize mass-manufactural UVB microlasers is reported. The gain coefficient at 289 nm is improv...

“…Huang et al experimentally demonstrate hybrid plasmonic nanolasers and nanolaser arrays based on MAPbX 3 perovskite nanosheets. The emission wavelengths of spasers were tuned more than 100 nm back and forth by changing the stoichiometry of perovskite by means of anion‐exchangeable method .

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.
