| description | The ongoing quest for ultra-compact optical devices has reached a bottleneck due
to the diffraction limit in conventional photonics. New approaches that provide
subwavelength optical elements, and therefore lead to miniaturization of the
entire photonic circuit, are urgently required. Plasmonics, which combines
nanoscale light confinement and optical-speed processing of signals, has the
potential to enable the next generation of hybrid information-processing
devices, which are superior to the current photonic dielectric components in
terms of speed and compactness. New plasmonic materials (other than metals), or
optical materials with metal-like behavior, have recently attracted a lot of
attention due to the promise they hold to enable low-loss, tunable,
CMOScompatible devices for photonic technologies. In this review, we provide a
systematic overview of various compact optical modulator designs that utilize a
class of the most promising new materials as the active layer or core— namely,
transparent conducting oxides. Such modulators can be made low-loss, compact,
and exhibit high tunability while offering low cost and compatibility with
existing semiconductor technologies. A detailed analysis of different
configurations and their working characteristics, such as their extinction
ratio, compactness, bandwidth, and losses, is performed identifying the most
promising designs. |
