“…Restricting the dimensions of the same wires in the transversal direction can be an effective tool to design the resonant cavity geometry. This can be achieved for instance with capillary bridge lithography [ 123 , 137 ]. This method exploits de-wetting of a liquid film deposited on a substrate by placing the solution in contact with a template of periodically arranged ribs with their surface modified with heptadecafluorodecyltrimethoxysilane ( Figure 12 a–c).…”

Organic semiconductor micro/nanocrystals (OSMCs) have attracted great attention due to their numerous advantages such us free grain boundaries, minimal defects and traps, molecular diversity, low cost, flexibility and solution processability. Due to all these characteristics, they are strong candidates for the next generation of electronic and optoelectronic devices. In this review, we present a comprehensive overview of these OSMCs, discussing molecular packing, the methods to control crystallization and their applications to the area of organic solid-state lasers. Special emphasis is given to OSMC lasers which self-assemble into geometrically defined optical resonators owing to their attractive prospects for tuning/control of light emission properties through geometrical resonator design. The most recent developments together with novel strategies for light emission tuning and effective light extraction are presented.

“…Also employing this method, our group recently prepared the NIR array and first achieved the nanolaser arrays over 760 nm. [ 29 ] Figure 6e was the PL microscopy image of ( E )‐3‐(4‐(dimethylamino)phenyl)‐1‐(1‐hydroxynaphthalen‐2‐yl)prop‐2‐en‐1‐one (DMHC) nanowires arrays with the length of 10 µm. The single DMHC nanowire was excited with a 532 nm laser (Figure 6c).…”

“…[ 13 ] Under excited with a certain power of a pulsed laser, nanowires show obvious stimulated emission behavior. [ 27–31 ] Nanowires of different lengths and diameters can form resonant cavities with different sizes, and single‐mode and multi‐mode lasing emission can be achieved, respectively. [ 32–34 ] In addition, by changing the doping ratios of the organic material, the ambient temperature, and the excitation energy of the pulsed laser, a wide‐spectrum tunable nanolaser based on OMNSs can be realized.…”

1D organic micro/nanostructures (OMNSs) based on π‐conjugated molecules are considered to be suitable candidates as photonic units due to their unique photophysical advantages over traditional ones in low‐temperature solution‐processed approach, tunable emission color, the built‐in cavity for optical confinement, and so forth. These inherent characteristics of OMNSs make them have broad application prospects in photonics devices, such as nanolasers, optical waveguides, and optical logical gates. In this review, the recent processes of OMNSs in terms of light generation, light confinement, and propagation are introduced, separately. Some representative works of OMNSs are discussed in the direction of optical modulation and processing. However, huge challenges still remain before the OMNSs are actually used as components of optical circuits in the photonics chips. The summary and the expectations are presented for the future development of 1D organic micro/nanostructures photonics.

“…Additionally, nanolaser arrays offer distinct advantages for some of these applications such as higher sensitivity compared to Raman-based sensors as well as a label-free imaging method [59,61]. The use of such arrays can also be extended to telecommunications, lab-on-a-chip applications, spectroscopy, and parallel detection [62][63][64]. Finally, integration of up to 11,664 nanolasers has already been demonstrated in a photonic crystal uncoupled array, underlining the feasibility of achieving even higher onchip packing density in the future [65].…”

Nanolaser arrays: toward application-driven dense integration

The past two decades have seen widespread efforts being directed toward the development of nanoscale lasers. A plethora of studies on single such emitters have helped demonstrate their advantageous characteristics such as ultrasmall footprints, low power consumption, and room-temperature operation. Leveraging knowledge about single nanolasers, the next phase of nanolaser technology will be geared toward scaling up design to form arrays for important applications. In this review, we discuss recent progress on the development of such array architectures of nanolasers. We focus on valuable attributes and phenomena realized due to unique array designs that may help enable real-world, practical applications. Arrays consisting of exactly two nanolasers are first introduced since they can serve as a building block toward comprehending the behavior of larger lattices. These larger-sized lattices can be distinguished depending on whether or not their constituent elements are coupled to one another in some form. While uncoupled arrays are suitable for applications such as imaging, biosensing, and even cryptography, coupling in arrays allows control over many aspects of the emission behavior such as beam directionality, mode switching, and orbital angular momentum. We conclude by discussing some important future directions involving nanolaser arrays.
