A phase-sensitive optical time domain reflectometer based on coherent heterodyne detection of geometric phase in the beat signal of light, is reported for the first time to our knowledge. The use of the geometric phase to extract strain makes it immune to polarisation diversity fading. This is ...
The degradation of second-harmonic generation in quasi-phase-matching waveguides, when random errors occur in the domain boundary position and when the effective index varies along the waveguide, is studied theoretically. Two models for random errors are used, one assuming independent shifts of the ...
Domain boundaries, i.e. interfaces between different orientation variants of the same crystal species, and phase boundaries, i.e. interfaces between two different modifications of the same compound, exhibit rather similar features. This has been investigated by means of polarized light and X-ray top...
Equation (3.121) was dealt with, separately, to discretize the equation in the time domain for the use of the semi-implicit numerical scheme. The key idea is that treating the linear terms implicitly can reduce the stability constraints; while treating the nonlinear term explicitly can avoid, ...
Although simulation software can model parasitic effects of converters, sample-based simulations in the time domain (using iterative numerical solvers) may be too computationally intensive for the fast iteration of design and control choices [23]. In addition, an in-depth analysis of the converter’...
As such, our work brings the fundamental wave feature of the Gouy phase to the quantum domain, thereby opening the path to its utilization in quantum technological applications through its unique quantum state manipulation properties. Probing the quantum Gouy phase An interferometric measurement scheme ...
[82]. Moreover, well-dispersed nano-domain coupling (WNC) heterostructures have attracted much attention in defect engineering. Due to the different band gaps of the WNC heterostructures at the nanoscale, the zone of hetero-phase interfaces can generate a built-in electric field, which provides ...
Male sexual function is measured via the International Index of Erectile Function (IIEF), a 15-item, multidimensional scale assessing various domains of male sexual function [68,69]. Item responses within each domain are summed to create subscale scores, and subscale scores are summed to create ...
The domain of the system is represented by intervals associated with each axis. Each interval represents the extent of the system on the corresponding axis. The interval data is managed by the object interval_data_type, which is a map that associates Axis values with instances of type interval...
