Improved emission outcoupling from microdisk laser by Si nanospheres

Laser particles with omnidirectional emission for cell tracking

“…Previous works on microlasers for on-chip applications mainly focused on directing the in-plane emission of WGM microlasers in a specific direction by introducing boundary deformations 11,[15][16][17][18][19] , diffraction gratings [20][21][22] , or scatterers [23][24][25][26] . Nevertheless, omnidirectional laser emission into 4π steradians has neither been attempted nor demonstrated.…”

Symmetry analysis and multipole classification of eigenmodes in electromagnetic resonators for engineering their optical properties

“…Their unique optical properties appear owing to Mie resonances, which can be excited even in the visible or near-infrared ranges for nanoscale particles [1][2][3]. Today dielectric particles with high refractive index have shown their for second [4][5][6][7] and third [8][9][10] harmonic generation, sensing [11], efficiency light localization [12], enhancement of the outcoupling radiation [13,14], excitation of guided modes [15][16][17][18], heating [19], enhancement of Raman scattering [20] etc. Along with low absorption in the visible and infrared ranges, an essential advantage of dielectric particles on their plasmonic counterpart is a pronounced magnetic response.…”
