Prof. Gauthier is interested in a broad range of topics in the
fields of nonlinear and quantum optics, and nonlinear
In the area of optical physics, his group is studying
the fundamental characteristics of highly nonlinear light-matter
interactions at both the classical and quantum levels and is using this understanding to develop practical
At the quantum level, his group has three major efforts in the area of quantum communication and networking. In one project, they are investigating hybrid quantum memories where one type of memory is connected to another through the optical field (so-called flying qubits). In particular, they are exploring nonlinear optical methods for frequency converting and impedance matching photons emitted from one type of quantum memory (e.g., trapped ions) to another (e.g., quantum dots).
In another project, they are exploring methods for efficiently transmitting a large number of bits of information per photon. They are encoding information on the various photon degrees of freedom, such as the transverse modes, one photon at a time, and using efficient mode sorters to direct the photons to single-photon detectors. The experiments make use of multi-mode spontaneous down conversion in a nonlinear crystal to produce quantum correlated or entangled photon pairs.
Another recent interest is the development of the world's most
sensitive all-optical switch. Currently, they have observed switching
with an energy density as low as a few hundred yoctoJoules per atomic
cross-section, indicating that the switch should be able to operate at
the single-photon level. The experiments use a quasi-one-dimensional ultra-cold gas of rubidium atoms as the nonlinear material. They take advantage of a one-dimensional optical lattice to greatly increase the nonlinear light-matter interaction strength.
In the area of nonlinear dynamics, his group is interested in the
control and synchronization of chaotic devices, especially optical and
radio-frequency electronic systems. They are developing new
methods for private communication of information using chaotic
carriers, using chaotic elements for distance sensing (e.g.,
low-probability-of-detection radar), using networks of chaotic elements
for remote sensing, and using chaotic elements for generating truly
random numbers at high data rates. Recently, the have observed 'Boolean chaos,' where complex behavior is observed in a small network of commercially-available free-running logic gates.
