“…Note that the matrix G is similar to Eqs. (4) and (5) of [9] for a two-disk laser, with the two-term sum of Hankel functions being replaced with an infinite lattice sum [1][2][3]. Note also that similar, but still different, transcendental or determinantal equations lie in the core of numerical threshold studies of other microcavity laser configurations reported in [10,11].…”

“…Probably also the near field solutions at resonances (scattered field part) generated by a computational treatment of specific scattering problems (Boriskina et al 2004Pishko et al 2007), for individual, suitably shaped cavities could be used for this purpose. A third alternative would be to employ real-frequency eigensolutions for the open, leaky individual cavities with artificial gain ("lasing eigenvalue problem" Smotrova and Nosich 2004;Smotrova et al 2006). …”

Chains of coupled square dielectric cavities are investigated in a 2-D setting, by means of a quasi-analytical eigenmode expansion method. Resonant transfer of optical power can be achieved along quite arbitrary, moderately long rectangular paths (up to 9 coupled cavities are considered), even with individual standing-wave resonators of limited quality. We introduce an ab-initio coupled mode model, based on a simple superposition of slab mode profiles as a template for the field of individual cavities. Although no loss mechanisms are built in, the model can still help to interprete the results of the former numerical experiments.

“…In the spectrum of a CROW composed of L microdisks, in place of every double-degenerate WGmode of a single disk L pairs of nearly-degenerate supermodes belonging to various symmetry classes arrear. Bonding WGsupermodes shift to longer wavelengths and anti-bonding supermodes shift to shorter wavelengths [21,31].…”

“…The continued drive for the miniaturization and dense packaging of photonic components has led to the development of ultra-small resonators made of high-index-contrast materials. To achieve efficient evanescent coupling between such resonators they should be brought very close to each other, which may significantly disturb WG-mode field patterns [6,7,21]. Furthermore, in the region of a sharp CROW bend strong evanescent-field coupling may occur between non-neighboring resonators.…”
