EPFL scientists have developed a new technique that lets researchers watch, with unprecedented sensitivity, how materials ...

Now, a team led by Professor Sascha Feldmann at EPFL’s Laboratory for Energy Materials has developed a high-sensitivity, ...

A new material developed at Penn State defies a fundamental law of physics, opening doors to highly efficient solar cells.

The LLSAW in lithium niobate on stress-free surface reveals rather high attenuation of the order of one dB per wavelength. Calculated resonant characteristics of a long IDT and dispersion curves of ...

The paper studies the optical solitons with coupled nonlinear Schrödinger system (CNLSS) that describes the propagation of waves in birefringence polarization-preserving fibers with four-wave mixing ...
