Abnormal high- modes of coupled stadium-shaped microcavities
Jung-Wan Ryu, Soo-Young Lee, Inbo Kim +3
It is well known that the strongly deformed microcavity with fully chaotic ray dynamics cannot support high-Q modes due to its fast chaotic diffusion to the critical line of refrac…
Terahertz beat freuquency generation from two-mode lasing operation of coupled microdisk laser
Jung-Wan Ryu, Jinhang Cho, Chil-Min Kim +2
We propose a coupled microdisk laser as a compact and tunable laser source for the generation of a coherent continuous wave THz radiation by photomixing. Using the Schrödinger-Bloc…
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…
Asymmetric scattering and non-orthogonal mode patterns in optical micro-spirals
Jan Wiersig, Sang Wook Kim, Martina Hentschel
Quasi-bound states in an open system do in general not form an orthogonal and complete basis. It is, however, expected that the non-orthogonality is weak in the case of well-confin…
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…
