CLEO: 2014, 2014
We demonstrate an integrated photonic electromagnetic field sensor based on an electro-optic polymer refilled slot photonic crystal waveguide modulator driven by a bowtie-antenna. The minimum detectable electric field is measured to be 2.5V/m at 8.4GHz.

The mechanical and electromagnetic (EM) properties of Si3N4 ceramic were improved by infiltrating SiC into porous Si3N4 ceramic by chemical vapor infiltration (CVI). After CVI of SiC, the Si3N4–SiC ceramic possesses improved mechanical properties, high permittivity and dielectric loss, and excellent EM shielding effectiveness and EM absorbing ...

An ultra-compact Electro-Magnetic (EM) Wave Sensor working at 14GHz is designed and demonstrated experimentally. The sensor is based on electro-optics (EO) modulation and therefore has several important advantages over conventional electrical RF sensors including compact size and immunity to electromagnetic interference (EMI).

AbstractUsing the AKR/J mouse model, the potential of Raman spectroscopy for monitoring lymphoma in predisposed subjects is demonstrated by discriminating lymphoma infiltration in spleens; the relevance of different excitation profiles is shown. Under green excitation with optimal fluorescence bleaching, stronger DNA bands, intensity variations at ...
