Designing Plasmonic Eigenstates for Optical Signal Transmission in Planar Channel Devices

Active planar lightwave devices for optical signal processing

Time-domain numerical analysis of nonlinear propagation in Slow-Wave-Structures, focused on the interplay of enhanced third-order nonlinearity with chromatic dispersion has been carried on. In dependence on the operating conditions, a tunable optical oscillator/pulse train generator and an optical limiter have been designed. Morphological inspection and functional characterization at λ=1.5 μm o...

Graphene Planar Plasmonic Waveguide Devices

Graphene has attracted great attention due to its extraordinary electronic, thermal, mechanical, and optical properties [1]. In photonics, graphene have been exhibited outstanding properties such as transparency, wavelength-independent optical absorption, satuable absorption, electron-hole pair generation, third-order nonlinearity, and electro-absorption. Graphene has been used as a transparent...

Planar holographic optical processing devices.

Time-domain optical processing implemented through linear spectral filtering offers unique potential for future high-bandwidth communications systems. One key to realization of this potential is the development of robust, cost-effective, fully integrated filtering devices. A new spectral filtering device concept, derived from the unique properties of index holograms stamped or otherwise written...
