(1)American University (Egypt) , (2)Ain Shams University (Egypt) Integration of electronic and photonic circuitries entails the design of on-chip ultra-compact electro-optical modulators. Here we introduce the design of a high performance electro-optical modulator structure based on an asymmetric hybrid plasmonic waveguide (AHPW) on a silicon-on-insulator (SOI) platform. The insertion loss and extinction ratio have been numerically verified by finite-difference time-domain simulations. The insertion loss is minimized for a 5 um modulator.
12:05 : Ultra-broadband plasmonic super absorbers for universal surface enhanced Raman spectroscopy substrate
Nan Zhang, Kai Liu, Haomin Song, Xie Zeng, Dengxin Ji, Qiaoqiang Gan
The State University of New York at Buffalo (USA) We developed an ultra-broadband super-absorbing metasurface substrate for SERS sensing. In contrast to conventional substrates working for limited excitation wavelengths, this structure can work for almost all available laser lines from 450 nm to 1000 nm.
