Label-Free Cancer Cells Detection Using Optical Sensors
IEEE Access, 2018 Rapid and accurate label-free-based discrimination techniques between normal and cancer cells play an important role in non-invasive screening systems. Significant differences in cell composition for normal and cancer cells have been reported.

Multi-Temporal Sentinel-1 and -2 Data Fusion for Optical Image Simulation
ISPRS International Journal of Geo-Information, 2018 In this paper, we present the optical image simulation from synthetic aperture radar (SAR) data using deep learning based methods. Two models, i.e., optical image simulation directly from the SAR data and from multi-temporal SAR-optical data, are ...

Modeling and Simulation of the Intrinsic Function of a Photonic Switch
Frontiers in Physics, 2018 In this paper, I provide modeling and simulation results which show that a photonic switch can be realized by the application of two superluminescent light emitting diodes to a configuration of three 10 μm radius micro-ring resonators. The 130 nm silicon
