“…The photonic crystal-like structure with a missing row can generate single-mode emission due to DFB effect. [47][48][49] In a DFB microcavity, light travels throughout the periodic structure, scattering from each point along its path. [50] Due to the wavelength selectivity of Bragg effect, an interference-induced single-mode emission at a structure-dependent wavelength can be obtained.…”

Single‐mode lasing with high‐beam quality and wide‐range spectral purity is of fundamental importance in scientific and technical applications. Lacking a mode selection strategy, achieving single whispering gallery mode (WGM)‐type lasing remains a challenge. Herein, a wide‐range tunable single‐WGM resonance in a mesh‐structured tubular microcavity is realized by combining WGM resonance with distributed feedback effect, and the single mode can be systematically and precisely tuned by tailoring the geometry parameters of the hole array. In addition, switching between single mode and multimode WGM can be achieved at different axial directions of one individual tubular microcavity. The structure provides additional degrees of freedom to manipulate the resonant spectra characteristics and the spatial distribution of resonant modes, thus having a promising future in micro‐/nano‐optical devices.

“…Fig. 1(a) shows a sketch of a MPC obtained by alternating slabs of length d 1 of a 45-degreetilted plain PhC and slabs of length d 2 of bulk material (n bulk = 2.9 corresponding to the effective refractive index at 1.55 µm of the suspended GaAs membrane described in [9]). For sake of simplicity and to preserve the feasibility, the slabs of PhC consist of an integer number of rows N row of a square-lattice (lattice constant a) of air hole (radius r = 0.28 a) etched into the same high-index material constituting the bulk slabs.…”

Mesoscopic self-collimation (MSC) in mesoscopic photonic crystals with high reflectivity is exploited to realize a novel high Q-factor cavity by means of mesoscopic PhC planar mirrors. These mirrors efficiently confine a mode inside a planar Fabry-Perot-like cavity, that results from a beam focusing effect that stabilizes the cavity even for small beam sizes, resembling the focusing behavior of curved mirrors. Moreover, they show an improved reflectivity with respect to their standard distributed Bragg reflector counterparts that allows higher compactness. A Q-factor higher than 10⁴ has been achieved for an optimized 5-period-long mirror cavity. The optimization of the Q-factor and the performances in terms of energy storage, field enhancement, and confinement are detailed.
