Nonlinear dynamical tunneling of optical whispering gallery modes in the presence of a Kerr nonlinearity
Jeong-Bo Shim, Peter Schlagheck, Martina Hentschel +1
The effect of a Kerr nonlinearity on dynamical tunneling is studied, using coupled whispering gallery modes in an optical microcavity. The model system that we have chosen is the '…
Nonorthogonal pairs of copropagating optical modes in deformed microdisk cavities
Jan Wiersig, Alexander Eberspächer, Jeong-Bo Shim +4
Recently, it has been shown that spiral-shaped microdisk cavities support highly nonorthogonal pairs of copropagating modes with a preferred sense of rotation (spatial chirality) […
Observation of an exceptional point in a chaotic optical microcavity
Sang-Bum Lee, Juhee Yang, Songky Moon +5
We present spectroscopic observation of an exceptional point or the transition point between diabatic crossing and avoided crossing of neighboring quasi-eigenmodes in a chaotic opt…
Regular Spectra and Universal Directionality of Emitted Radiation from a Quadrupolar Deformed Microcavity
Jeong-Bo Shim, Hai-Woong Lee, Sang-Bum Lee +5
We have investigated quasi-eigenmodes of a quadrupolar deformed microcavity by extensive numerical calculations. The spectral structure is found to be quite regular, which can be e…
Universal output directionality of ultrahigh-Q single modes in a deformed microcavity with low index of refraction
Sang-Bum Lee, Jeong-Bo Shim, Sang Wook Kim +5
Experimental investigation of the characteristics of quasi-bound states of a quadrupole deformed microcavity has revealed five distinct mode groups in cavity emission spectra with…
Development of deformation-tunable quadrupolar microcavity
Juhee Yang, Songky Moon, Sang-Bum Lee +5
We have developed a technique for realizing a two-dimensional quadrupolar microcavity with its deformation variable from 0% to 20% continuously. We employed a microjet ejected from…
