Integrated Silicon Nanophotonic Data Processing Devices: A Brief Review
Significant scientific efforts are constantly invested in the attempts to develop photonic circuitry integrated in
microelectronic chip. Such circuitry should be capable of realizing fundamental processing building blocks such as
modulators (or transistors) and logic gates in order to improve the performance of an optics communication short and/or
long range links. The improvement is to be obtained in the sense of reduced power dissipation, lower noise level and
increased information bandwidth. This paper reviews some of the technologies involved in those efforts. Specifically we
focus on silicon based integrated nanophotonic modulation devices (based upon plasma dispersion as well as fundamental
non linear processes in silicon) as well as passive devices for directing and spectrally filtering light via silicon
nanophotonic crystal structures. The patents mentioned in this review relate to the realization of nanophotonic logic gates
for data processing, they are related to photonic nano communication link apparatus, apparatus and method for switching,
modulation and dynamic control of light transmission using photonic crystals and to modulator-based photonic chip-tochip
interconnections for dense three-dimensional multichip module integration.
