Integrated ray-wave optics modeling for macroscopic diffractive lighting devices.
Optics Express, 2019 We studied a high-accuracy hybrid optics modeling for macroscopic lighting devices containing highly diffractive elements. For a two-dimensional (2D) grating, we achieved forward and backward diffraction distributions at omnidirectional incidence by ...

Towards standardization of compact data center switches
ICT Express, 2017 Data Centers, the essential infrastructure for the increasing amount of cloud applications, are required to expand in number of devices even further. However, the scaling is limited by both space and power constraints. It is therefore essential to shrink
