On the use of deep learning for phase recovery
Kaiqiang Wang, Li Song, Chutian Wang +8
Phase recovery (PR) refers to calculating the phase of the light field from its intensity measurements. As exemplified from quantitative phase imaging and coherent diffraction imag…
Unified treatment of exact and approximate scalar electromagnetic wave scattering
Subeen Pang, George Barbastathis
Under conditions of strong scattering, a dilemma often arises regarding the best numerical method to use. Main competitors are the Born series, the Beam Propagation Method, and dir…
xSCYTE: Express Single-frame Cytometer through Tomographic Phase
Baoliang Ge, Yanping He, Mo Deng +13
Rapid, comprehensive, and accurate cell phenotyping without compromising viability, is crucial to many important biomedical applications, including stem-cell therapy, drug screenin…
Imaging through glass diffusers using densely connected convolutional networks
Shuai Li, Mo Deng, Justin Lee +2
Computational imaging through scatter generally is accomplished by first characterizing the scattering medium so that its forward operator is obtained; and then imposing additional…
Coherence retrieval using trace regularization
Chenglong Bao, George Barbastathis, Hui Ji +2
The mutual intensity and its equivalent phase-space representations quantify an optical field's state of coherence and are important tools in the study of light propagation and dyn…
Tapered Simplified Modal Method for Analysis of Non-rectangular Gratings
Shuai Li, Changhe Zhou, George Barbastathis
The Simplified Modal Method (SMM) provides a quick and intuitive way to analyze the performance of gratings of rectangular shapes. For non-rectangular shapes, a version of SMM has…
Hamiltonian and Phase-Space Representation of Spatial Solitons
Hanhong Gao, Lei Tian, George Barbastathis
We use Hamiltonian ray tracing and phase-space representation to describe the propagation of a single spatial soliton and soliton collisions in a Kerr nonlinear medium. Hamiltonian…
Compressive X-ray phase tomography based on the transport of intensity equation
Lei Tian, Jonathan C. Petruccelli, Qin Miao +3
We develop and implement a compressive reconstruction method for tomographic recovery of refractive index distribution for weakly attenuating objects in a microfocus X-ray system.…
Design of thin-film photonic metamaterial Lüneburg lens using analytical approach
Hanhong Gao, Baile Zhang, Steven G. Johnson +1
We design an all-dielectric Lüneburg lens as an adiabatic space-variant lattice explicitly accounting for finite film thickness. We describe an all-analytical approach to compensat…
Affine nonmagnetic transformation optics and its application to a practical bending adapter design
Hongyi Xu, Baile Zhang, Tianyuan Yu +2
One of the bottlenecks that limit the transition of transformation-optics devices from concepts to practical use is the non-unit magnetic permeability generally required from a mat…
Broadband phase-preserved optical elevator
Yuan Luo, Tiancheng Han, Baile Zhang +2
Phase-preserved optical elevator is an optical device to lift up an entire plane virtually without distortion in light path or phase. Using transformation optics, we have predicted…
Experimental compressive phase space tomography
Lei Tian, Justin Lee, Se Baek Oh +1
Phase space tomography estimates correlation functions entirely from snapshots in the evolution of the wave function along a time or space variable. In contrast, traditional interf…
Macroscopic Invisibility Cloak for Visible Light
Baile Zhang, Yuan Luo, Xiaogang Liu +1
Invisibility cloaks, a subject that usually occurs in science fiction and myths, have attracted wide interest recently because of their possible realization. The biggest challenge…
