“…The ordered arrays possess the combined properties of particle plasmons and diffractive modes (see Figure c), also known as plasmonic hybridization . At the SLR conditions the incoming light is trapped inside the lattice plane and leads to a narrow full width at half maximum (FWHM or line width) and strongly enhanced local electric fields at the nanoparticle surface . This occurs due to the constructive interference and coherent coupling at the SLR position which leads to the standing wave formation and hence allows for localized field enhancement.…”

“…Both conditions can be overcome by utilizing SLRs instead of LSPRs for creating an optical feedback. The combination of elastomeric substrates and lattice resonances has been foremost studied by the group of Odom, who investigated the behavior of different lattice geometries prepared. Aside from this lithography‐based work, colloidal self‐assembly enables the preparation of plasmonic lattices on elastomers like PDMS.…”

Noble metal nanoparticles can absorb incident light very efficiently due to their ability to support localized surface plasmon resonances (LSPRs), collective oscillations of the free electron cloud. LSPRs lead to strong, nanoscale confinement of electromagnetic energy which facilitates applications in many fields including sensing, photonics, or catalysis. In these applications, damping of the LSPR caused by inter‐ and intraband transitions is a limiting factor due to the associated energy losses and line broadening. The losses and broad linewidth can be mitigated by arranging the particles into periodic lattices. Recent advances in particle synthesis, (self‐)assembly, and fabrication techniques allow for the realization of collective coupling effects building on various particle sizes, geometries, and compositions. Beyond assemblies on static substrates, by assembling or printing on mechanically deformable surfaces a modulation of the lattice periodicity is possible. This enables significant alteration and tuning of the optical properties. This progress report focuses on this novel approach for tunable spectroscopic properties with a particular focus on low‐cost and large‐area fabrication techniques for functional plasmonic lattices. The report concludes with a discussion of the perspectives for expanding the mechanotunable colloidal concept to responsive structures and flexible devices.

“…Besides the above‐mentioned systems, many other configurations for plasmonic lasers have been demonstrated using cavity modes from surface lattice plasmon mode in metal nanoparticles array, Tamm SPP mode, long‐range SPP mode, random mode to other diverse modes . Also, by operating at NIR region with relatively low metal losses, metal‐cladded 3D‐confined subdiffraction‐limit plasmonic nanolasers have been demonstrated, in which the cladding metals support TM cavity modes and behave more like perfect reflecting mirrors .…”

and techniques have been proposed and/ or developed. Here we focus on a newly emerging area-plasmonic nanolaser that pursuing extremely smaller cavity size in one or more dimensions, and consequently extreme lasing conditions, by using a plasmonic cavity with feature size possibly far below the diffraction limit of light.The miniaturization of a laser can be traced back to the early age of the laser, when compact semiconductor structures were introduced. In particular, the introduction of semiconductors as the gain media in 1962, [11,12] followed by a series of elaborately engineered structures from heterostructure, [13] quantum well, [14] vertical-cavity surface-emitting laser (VCSEL), [15,16] microdisk, [17][18][19] photonic crystal, [20][21][22] quantum dot [23,24] to nanowire (NW) [25][26][27] have made great success in shrinking a laser from bulk scale to wavelength level using reduced cavity sizes. [28] For example, to date, typical commercial edgeemitting quantum well laser diodes have dimensions of several micrometers in width and hundreds of micrometers in length, and a single quantum dot can lase in a photonic crystal cavity with overall dimension of merely 0.7(λ/n) 3 , where λ is the vacuum wavelength and n the refractive index of the dielectric. [29] With optimized geometry and material for cavity design, lower structural dimension is expected. However, in a dielectric cavity with limited refractive index n, the cavity size is intrinsically restricted by optical diffraction limit that sets an ultimate limit λ/2n for both cavity length and mode size in all three dimensions.An effective step to shrink a cavity beyond the diffraction limit is converting light into surface plasmon polaritons (SPPs) in nanostructuralized metals, which is a kind of collective oscillation of quasi free electrons on the interface of a metal and a dielectric. [30] While SPP is featured with ultrahigh optical confinement and ultrafast relaxation process as shown in Figure 1a, [31] it is inevitably accompanied by ultrahigh energy dissipation (i.e., Ohmic loss), leading to a mutual balance between the mode size and the optical loss in either a nanowaveguide or a nanocavity as shown in Figure 1b. [32] For example, the transverse mode area of SPP mode on an Ag nanowire with diameter of 100 nm can be as small as 0.01 µm 2 but also exhibits a propagation loss larger than 200 dB mm −1 . Despite of the high loss coefficient of plasmonic resonance at optical frequency, a properly designed nanoplasmonic cavity coupled with a gain medium is possible to lase with miniature cavity length.Owing to their ultrahigh optical confinement, plasmonic nanolasers with cavity sizes beyond the diffraction limit of light, are attracting increasing attention for pursuing extreme lasing conditions on nanoscale including ultracompact cavity mode, ultrafast lasing modulation, significantly enhanced light-matter interaction, and Purcell effect. In this review, the recent progress on plasmonic nanolasers from both theoretical and experimental aspects is intro...

“…In this approach, changing the geometry of the cavity structure or the refractive index of the cavity results in changes in the resonance modes and free spectral range, which can be utilized to select specific lasing wavelengths. The importance of cavity design lies in two factors: (1) A MNL with a particular structure can be made tunable by changing the resonators; (2) The variable wavelength only lases when the newly designed cavity satisfies the threshold condition …”

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.
