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…
Chaos-assisted nonresonant optical pumping of quadrupole-deformed microlasers
Sang-Bum Lee, Jeong-Bo Shim, Sang Wook Kim +4
Efficient nonresonant optical pumping of a high-Q scar mode in a two-dimensional quadrupole-deformed microlaser has been demonstrated based on ray and wave chaos. Three-fold enhanc…
