“…The resonators used for lasing can be divided into three groups: random resonators, supporting random lasing (RL); [ 2–6 ] optical resonators based on the refractive index contrast between the synthesized perovskite material and air, such as micro‐ and nanocubes, [ 7–9 ] rods, [ 10,11 ] wires, [ 12–17 ] platelets, [ 18–20 ] micropyramids, [ 21 ] and microspheres; [ 22–24 ] and external resonators based on distributed Bragg reflectors, [ 25–28 ] capillary‐like microcavities, [ 29 ] photonic crystals, [ 30,31 ] gratings for distributed feedback lasers, [ 32–38 ] and nanolithographically fabricated microdisks. [ 39–41 ] The laser generation manifests itself in different ways. In most of the works, the main conclusion about the lasing nature of the emission is made based on the narrow line width and threshold behavior [ 2–5,7–16,18,19,21,22,25–27,30,32–43 ] of the emission.…”

Halide perovskites are a promising optical gain medium with high tunability and simple solution synthesis. In this study, two gain regimes, namely, amplified spontaneous emission and random lasing, are demonstrated in the same MAPbBr3 halide perovskite single crystal. For this, photoluminescence is measured at a temperature of 4 K with pulsed femtosecond pumping by UV light with an 80 MHz repetition rate. Random lasing is observed in areas of the sample where a random resonator is formed due to cracks and crystal imperfections. In more homogeneous regions of the sample, the dominant regime is amplified spontaneous emission. These two regimes are reliably distinguished by the line width, the mode structure, the growth of the intensity after the threshold, and the degree of polarization of the radiation. The spectral localization of the stimulated emission well below the bound exciton resonance raises a question concerning the origin of the emission in halide perovskite lasers.

In the past decade, lead halide perovskites have been intensively explored due to their promising future in photovoltaics. Owing to their remarkable material properties such as solution processability, nice defect tolerance, broad bandgap tunability, high quantum yields, large refractive index, and strong nonlinear effects, this family of materials has also shown advantages in many other optoelectronic devices including microlasers, photodetectors, waveguides, and metasurfaces. Very recently, the stability of perovskite devices has been improved with the optimization of synthesis methods and device architectures. It is widely accepted that it is the time to integrate all the perovskite devices into a real system. However, for integrated photonic circuits, the shapes and distributions of chemically synthesized perovskites are quite random and not suitable for integration. Consequently, controlled synthesis and the top‐down fabrication process are highly desirable to break the barriers. Herein, the developments of patterning and integration techniques for halide perovskites, as well as the structure/function relationships, are systematically reviewed. The recent progress in the study of optical responses originating from nanostructured perovskites is also presented. Lastly, the challenges and perspective for nanostructured‐perovskite devices are discussed.

Date back to the first introduction of organic-inorganic hybrid perovskites into solar cells in 2009, [5] the power conversion efficiencies (PCEs) have been greatly boosted from 3.8% to 25.2% (certified PCEs) during the past decade. [6] With the merits of excellent photoluminescence (PL) quantum yield, perovskite-based light-emitting diodes (LEDs) have achieved external quantum efficiency (EQE) exceeding 20% via defect passivation, structural modification, and surface engineering. [7-9] In addition to the prosperity in photovoltaic and light-emitting devices, tremendous efforts are carried on the MHPs pursuing ultra-low threshold laser, [10,11] and ultra-sensitive photo-and X-ray detectors. [12-14] Solution processing method is commonly used for fabricating perovskite thin films. This cost-effective method allows large-scale production of smooth and uniform perovskite thin films served as the active layers of solar cells. [15] However, it is difficult to grow specific nano/microcrystals with desired dimensions and positions to meet the requirement of integrated electronic and optoelectronic devices with compactness. Patterning technology is widely used in optoelectronic fields to improve device performance. Performing various patterning technologies on materials not only obtain aesthetic value but also generate specific functions through constructing ordered and well-designed structures. [16-19] Specific structures and periodic patterns endow materials with unique light-matter interaction which has great impacts on photovoltaic and optoelectronic devices. [20] Moreover, patterning technologies can construct highresolution patterns down to nanoscale resolution, which meets the requirement for displaying and anti-counterfeiting applications. Therefore, performing versatile patterning technologies on MHPs would not only improve their electronic and optical properties but also opens a new pathway for integrated electronic and optoelectronic systems with unique and novel functions. Here, an overview of the recent advances of patterning technology in the field of MHPs is presented (Figure 1). The patterning technologies were divided into two parts based on whether patterned templates are required. With the merits of patterning technologies, the patterned MHPs exhibited novel functions and enhanced performance in optical and optoelectronic applications, such as solar cells, photodetectors, laser, anti-counterfeiting, and full-color displays. Therefore, the relationship between the patterned structures and the MHPs device performance as well as the corresponding mechanisms are discussed in detail. Finally, a summary and some perspectives on the existing challenges of patterned MHPs are put forward. Metal halide perovskites (MHPs), as emerging stars, are greatly attracted due to their superior optical and optoelectrical properties. The design and construction of patterned materials have been considered as a powerful tool to improve the performance of optical and optoelectronic devices. Therefore, the marriage of MHPs and ...
