Transformation cavities with a narrow refractive index profile
Jung-Wan Ryu, Jinhang Cho
Recently, gradient index cavities, or so-called transformation cavities, designed by conformal transformation optics have been studied to support resonant modes with both high Q-fa…
Circle-shaped Transformation Cavity via Center-Shift Möbius Transfomation
Jinhang Cho, Inbo Kim, Sunghwan Rim +3
Circle-shaped transformation cavities of shifted center are the most simple transformation cavities in the sense that they have only spatial index variation without boundary shape…
Boundary integral equation method for resonances in gradient index cavities designed by conformal transformation optics
Jung-Wan Ryu, Jinhang Cho, Soo-Young Lee +5
In the case of two-dimensional gradient index cavities designed by the conformal transformation optics, we propose a boundary integral equation method for the calculation of resona…
Optimization of conformal whispering gallery modes in limaçon-shaped transformation cavities
Jung-Wan Ryu, Jinhang Cho, Inbo Kim +1
In limaçon-shaped gradient index dielectric cavities designed by conformal transformation optics, the variation of Q-factors and emission directionality of resonant modes was trace…
