“…Notably, the lasing threshold is found to be as low as ≈2 μJ cm −2 and the linewidth of the lasing peak is as narrow as 0.14 nm, indicating the high performance of the CsPbX 3 microlasers. In addition, two‐ as well as three‐photon‐pumped lasing has been realized from CsPbX 3 nanostructures, such as the nanorods with triangular cross sections and nanocubes, which suggests that these CsPbX 3 nanostructures are highly appealing in frequency up‐converted lasing devices and on‐chip integrated photonics. Table 2 summarizes the major findings of stimulated emission and lasing from CsPbX 3 nanostructures.…”

decay arising from the defect-state trapping dominates carrier recombination, which results in a typically low photoluminescence quantum yield (PLQY) (<30%), especially under low carrier-injection densities (≈10 15 cm −3 ), comparable to that under LED working conditions. [5,6,[12][13][14][15] Hence, spontaneous free-carrier generation following light absorption in OIHPs, which explains the high photoconversion efficiency, becomes the obstacle to improving their light-emission performance.[5] Second, these OIHPs are extremely sensitive to the moisture, oxygen, and heat, which has been found to be closely related to the existence of the organic component, thereby incurring a constraint of a critical environment for fabrication, storage, and device operation, commonly notorious in organic photonic materials.Fortunately, the above limitations of OIHPs can be simultaneously overcome by exploiting all-inorganic metal halide perovskite nanostructures (IHPNs), a closely related family of materials. The all-inorganic constituents with intrinsically higher melting and decomposition points allow improved photo-and thermostability, as well as higher resistance to the atmosphere, and the enhanced exciton binding energies in the perovskite nanostructures ensure stable excitonic emission at room temperature. In early 2015, Protesescu et al. reported pioneering work on all-inorganic cesium lead halide (CsPbX 3 , X = Cl, Br, and I) light-emitting nanocrystals. [16] Immediately after their report, there was an explosion of research activity on IHPNs motivated by their superior optical properties and the low cost of the synthetic methods. [16][17][18] Compared to the canonical CdSe quantum dots, which have developed for more than two decades, [19] the emerging all-inorganic CsPbBr 3 perovskite nanocrystals exhibit even better emission characteristics, including higher PLQY (a PLQY of 100% was recently achieved [20] ) and narrower emission linewidth (<20 nm). [16,18,21,22] Moreover, while a high temperature (280 °C) and a protective atmosphere are required for synthesis of CdSebased quantum dots, the fabrication of CsPbX 3 nanocrystals can be performed at room temperature and free from an inert environment. [18] Leveraging on the halide composition control, the emission wavelength of CsPbX 3 nanocrystals can be finely tuned across the whole visible spectral range, enabling a wide color gamut. [16] Especially, the facile fabrication of high-quality blue-green-emitting (410-530 nm) CsPbX 3 nanocrystals makes them more competitive against traditional metal-chalcogenide nanocrystals, which typically suffer from photodegradation and relatively poor PLQY in the visible short-wavelength range. [16] All-inorganic metal halide perovskite nanostructures (IHPNs) have sparked intense research interest by virtue of their superior optical properties and their cost-effective synthesis. Since the first report in 2015, striking development of IHPNs has been witnessed in terms of fabrication strategies, optical characterization, and optoelectronic a...

The understanding of nonlinear light−matter interactions at the nanoscale has fueled worldwide interest in upconversion emission for imaging, lasing, and sensing. Upconversion lasers with anti-Stokes-type emission with various designs have been reported. However, reducing the volume and lasing threshold of such lasers to the nanoscale level is a fundamental photonics challenge. Here, we demonstrate that the upconversion efficiency can be improved by exploiting single-mode upconversion lasing from a single organo-lead halide perovskite nanocrystal in a resonance-adjustable plasmonic nanocavity. This upconversion plasmonic nanolaser has a very low lasing threshold (10 μJ cm −2 ) and a calculated ultrasmall mode volume (∼0.06 λ 3 ) at 6 K. To provide the unique feature for lasing action, a temporal coherence signature of the upconversion plasmonic nanolasing was determined by measuring the second-order correlation function. The localized-electromagnetic-field confinement can be tailored in titanium nitride resonance-adjustable nanocavities, enhancing the pump-photon absorption and upconverted photon emission rate to achieve lasing. The proof-of-concept results significantly expand the performance of upconversion nanolasers, which are useful in applications such as on-chip, coherent, nonlinear optics, information processing, data storage, and sensing.

“…Such frequency upconversion nonlinear absorption processes feature several merits including large penetration depth and high spatial resolution, as well as little photodamage and photobleaching. , The larger penetration length within the samples offers more opportunities for investigating the inner physical nature of materials and also effectively suppresses nonradiative recombination due to surface defects . Moreover, the multiphoton-pumped process has fascinating characteristics such as repression of unwanted absorption losses . Consequently, multiphoton-pumping is a feasible and important technique to generate the nonlinear luminescence for halide perovskites due to their large absorption cross sections, stable excitons at room temperature, and strong oscillator strength, , leading to further applications in optical data storage, characterization of ultrafast optical signals, and optical limiting …”

Organometallic halide perovskites have been demonstrated to be very promising for nonlinear optics and practical frequency upconversion devices in integrated photonics. In this work, high quality organometallic halide CH 3 NH 3 PbBr 3 perovskite thin films were synthesized through a solution-based one-step spin-coating method. With femtosecond optical pumping at 1300 nm, frequency-upconverted random lasing (RL) from the bromide perovskite films were achieved via three-photon (3P) absorption processes. The RL spectra show no spikes due to the large scattering mean-free path in the perovskite crystals, meaning the incoherent RL emission with incoherent feedback. In comparison with the one-photon pumped situation, it is found that both the two-photon and 3P excitations are more effective in reducing the RL threshold, despite the low conversion efficiency of their nonlinear multiphoton schemes. Moreover, the time-and spectralresolved lasing characteristics of the laser pulses were systematically explored by time-resolved photoluminescence based on an optical Kerr-gate method. The measured ultrashort 3.1 ps output pulse is the shortest one that has been observed so far in bromide perovskite random lasers, without any postprocessing. In addition, wavelength dependence of the pulse width and delay time of the RL pulses were clearly demonstrated, and could be unravelled by intraband carrier relaxation dynamics, which is an important physical mechanism in ultrafast lasers. Our results demonstrate that organometallic halide perovskites are excellent gain medium for high-performance frequency upconversion random lasers and have great potential for use in gain-switched semiconductor lasers with ultrashort output pulses and tunable emission wavelengths across the entire visible spectrum.
