Timing jitter optimization of mode-locked Yb-fiber lasers toward the attosecond regime
Youjian Song, Chur Kim, Kwangyun Jung +2
We demonstrate ultra-low timing jitter optical pulse trains from free- running, 80 MHz repetition rate, mode-locked Yb-fiber lasers. Timing jitter of various mode-locking condition…
Near-field examination of perovskite-based superlenses and superlens-enhanced probe-object coupling
Susanne C. Kehr, Yongmin M. Liu, L. W. Martin +11
A planar slab of negative index material works as a superlens with sub-diffraction-limited imaging resolution, since propagating waves are focused and, moreover, evanescent waves a…
Impact of pulse dynamics on timing jitter in mode-locked fiber lasers
Youjian Song, Kwangyun Jung, Jungwon Kim
We investigate the high-frequency timing jitter spectral density of mode-locked fiber lasers in different mode-locked regimes. Quantum noise-limited timing jitter spectra of mode-l…
Characterizing and tracking single colloidal particles with video holographic microscopy
Sang-Hyuk Lee, Yohai Roichman, Gi-Ra Yi +5
We use digital holographic microscopy and Mie scattering theory to simultaneously characterize and track individual colloidal particles. Each holographic snapshot provides enough i…
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…
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…
