Massively parallel ultrafast random bit generation with a chip-scale laser
Kyungduk Kim, Stefan Bittner, Yongquan Zeng +4
Random numbers are widely used for information security, cryptography, stochastic modeling, and quantum simulations. Key technical challenges for physical random number generation…
Non-invasive optical focusing inside strongly scattering media with linear fluorescence
Dayan Li, Sujit Kumar Sahoo, Huy Quoc Lam +2
Non-invasive optical focusing inside scattering media is still a big challenge because inhomogeneous media scatter both incoming photons for focusing and outgoing photons for obser…
Spatial structure of lasing modes in wave-chaotic semiconductor microcavities
Stefan Bittner, Kyungduk Kim, Yongquan Zeng +2
We present experimental and numerical studies of broad-area semiconductor lasers with chaotic ray dynamics. The emission intensity distributions at the cavity boundaries are measur…
Multimode Lasing in Wave-Chaotic Semiconductor Microlasers
Alexander Cerjan, Stefan Bittner, Marius Constantin +5
We investigate experimentally and theoretically the lasing behavior of dielectric microcavity lasers with chaotic ray dynamics. Experiments show multimode lasing for both D-shaped…
Noninvasive super-resolution imaging through scattering media
Dong Wang, Sujit Kumar Sahoo, Cuong Dang
Super-resolution imaging with advanced optical systems has been revolutionizing technical analysis in various fields from biological to physical sciences. However, many objects are…
Electrically pumped semiconductor laser with low spatial coherence and directional emission
Kyungduk Kim, Stefan Bittner, Yongquan Zeng +3
We design and fabricate an on-chip laser source that produces a directional beam with low spatial coherence. The lasing modes are based on the axial orbit in a stable cavity and ha…
Suppressing spatio-temporal lasing instabilities with wave-chaotic microcavities
Stefan Bittner, Stefano Guazzotti, Yongquan Zeng +7
Spatio-temporal instabilities are widespread phenomena resulting from complexity and nonlinearity. In broad-area edge-emitting semiconductor lasers, the nonlinear interactions of m…
Anomalous Spectral Characteristics of Ultrathin sub-nm Colloidal CdSe Nanoplatelets
Sumanta Bose, Savas Delikanli, Aydan Yeltik +6
We demonstrate high quantum yield broad photoluminescence emission of ultrathin sub-nanometer CdSe nanoplatelets (two-monolayer). They also exhibit polarization-characterized later…
Single shot large field of view imaging with scattering media by spatial demultiplexing
Sujit Kumar Sahoo, Dongliang Tang, Cuong Dang
Optically focusing and imaging through strongly scattering media are challenging tasks but have widespread applications from scientific research to biomedical applications and dail…
Enhancing security of optical cryptosystem with position-multiplexing and ultra-broadband illumination
Dongliang Tang, Sujit Kumar Sahoo, Cuong Dang
A position-multiplexing based cryptosystem is proposed to enhance the information security with an ultra-broadband illumination. The simplified optical encryption system only conta…
The transition from quantum field theory to one-particle quantum mechanics and a proposed interpretation of Aharonov-Bohm effect
Benliang Li, Daniel W. Hewak, Qi Jie Wang
In this article we demonstrate a sense in which the one-particle quantum mechanics (OPQM) and the classical electromagnetic four-potential arise from quantum field theory (QFT). In…
