“…Figure 3(d) shows the numerically calculated quality (Q) factors of resonances inside the cavity. Here the cavity structures and refractive index were all taken from experimental data and material dispersions have been considered28. Due to the relative large refractive index of hybrid lead halide perovskite, the cavity can support a number of resonant modes.…”

Hybrid lead halide perovskites have made great strides in next-generation light-harvesting and light emitting devices. Recently, they have also shown great potentials in nonlinear optical materials. Two-photon absorption and two-photon light emission have been thoroughly studied in past two years. However, the three-photon processes are rarely explored, especially for the laser emissions. Here we synthesized high quality CH3NH3PbBr3 perovskite microstructures with solution processed precipitation method and studied their optical properties. When the microstructures are pumped with intense 1240 nm lasers, we have observed clear optical limit effect and the band-to-band photoluminescence at 540 nm. By increasing the pumping density, whispering-gallery-mode based microlasers have been achieved from CH3NH3PbBr3 perovskite microplate and microrod for the first time. This work demonstrates the potentials of hybrid lead halide perovskites in nonlinear photonic devices.

“…Very recently, some efforts have been taken into the spatially controlled or composition‐graded halide perovskites MNL, which are promising to play a key role in their applications in micro/nanoscale photonic devices. By postsynthetic and control of the optical properties of lead halide perovskites, including wavelengths of absorption, PL, and lasing, Song and co‐workers realized the blueshifted wavelength range of around 50 nm . Combined with nanofabrication, the anion‐exchange chemical techniques have been proved to be very useful in precisely controlling the spatial patterns of multicolor CsPbX 3 (X = Cl, Br, I, or alloy of two halides) NWs in Yang's work .…”

Micro/nanolasers (MNLs) emit coherent light on the micro/nanoscale. Research on the application of MNLs has progressed rapidly in the past two decades because of their great potential for optoelectronics with compact sizes, low cost, and low energy consumption. Wavelength‐tunable MNLs are essential for a variety of fields including optical communications, solid‐state lighting, and on‐chip wavelength‐division multiplexing. Thus far, tremendous progress is achieved toward the development of wavelength‐tunable MNLs based on bandgap tuning and cavity design. Lasing wavelength is substantially defined by material bandgap, tuned by changing the geometry of the cavity structures, and can also, to some extent, be influenced by operational environment. This review is focused on the intrinsic merits of wavelength‐tunable MNLs, and the recent progress is examined. Bandgap engineering, materials synthesis, cavity structure design, wavelength‐tuning principles, and lasing performance are explored and systematically discussed. Finally, the current research status and perspectives on possible future applications are summarized.

“…This new technology is believed to be able to compete with the commercial thin‐film solar cells based on materials like silicon, cadmium telluride (CdTe) and copper–indium–gallium–diselenide (CIGS) . Concomitant with the flourishing research of PVK solar cells and thanks to the extensive efforts on synthesize and properties exploration, the utilization of PVKs in photonic and optoelectronic devices like lasers, light emitting diodes (LEDs), photodetectors, transistors, and phototransistors has received increasing attention.…”

The recent emergence of metal-halide perovskites as light absorbers in solar cells has attracted lots of attention on their synthesis and properties. In particular, low-dimensional metal-halide perovskites like platelets and wires are expected to regulate their optical and electrical properties in reference to bulk counterparts as a result of quantum confinement and anisotropy. In this review, first, the recent solution-and vapor-based approaches on synthesizing metal-halide perovskite platelets and wires are highlighted. Then, their optical and electrical properties along with application in photonics and optoelectronics such as lasers, light emitting diodes, photodetectors, and phototransistors are discussed. At last, the importance of such perovskite platelets and wires on improving material stability and transport properties is emphasized, and potential integration of perovskites with other lowdimensional materials in multifunctional systems is proposed.
