Journal ArticleDOI
Observation of an exceptional point in a chaotic optical microcavity.

TL;DR: A singular topology was observed around the exceptional point on the eigenfrequency surfaces, resulting in fundamental inconsistency in mode labeling in a chaotic optical microcavity of a large size parameter.
Journal ArticleDOI
Observation of scarred modes in asymmetrically deformed microcylinder lasers.
TL;DR: O observation of lasing in the scarred modes in an asymmetrically deformed microcavity made of liquid jet corresponds to morphology-dependent resonance of radial mode order 3 with their Q values in the range of 10(6).
Journal ArticleDOI
Dynamics of cascaded Brillouin-Rayleigh scattering in a distributed fiber Raman amplifier.
TL;DR: The extended effective length for the relevant nonlinear processes from the distributed Raman gain and the reduced Brillouin threshold from the seeding effect of Rayleigh backscattered waves are considered to be the key factors that explain the operation of this structure.
Journal ArticleDOI
Universal output directionality of single modes in a deformed microcavity
Sang-Bum Lee,Juhee Yang,Songky Moon,Jai-Hyung Lee,Kyungwon An,Jeong-Bo Shim,Hai-Woong Lee,Sang Wook Kim +7 more
TL;DR: In this paper, S.B.S. and H.W.L.K. were supported by a grant from KRISS and by KOSEF Grant No. R01-2005-000-10678-0.
Journal ArticleDOI
Control of epitaxial growth of pulsed laser deposited LiNbO3 films and their electro‐optic effects
TL;DR: In this article, the birefringence measurements of the LiNbO3 (1120) film showed a quadratic electro-optic behavior with an effective quadrastic coefficient of 2.38×10−15 m2/V2.
