Nanophotonics: Manipulating Light on a Nanoscale
Optics on chip can provide high bandwidth, high speed and ultra-small
optoelectronic components. In order to realize this technology one needs to
overcome several critical barriers such as coupling to and from the chip,
"packing" effective long lengths into micron-sized structures to enable for
example optical buffers, and achieving on-chip light modulation.
In this talk I will review the physics and applications of nanophotonics and
address the above critical barriers. I will present structures that allow
95% fiber to waveguide coupling in short lengths using high index contrast
Si/SiO2 materials. I will also present Si micron-size structures that
enable to modulate light on Silicon with very low powers.
