The end result is an image far sharper and clearer than could be obtained in the optical domain alone.

OAM multiplexing looks much more promising in the optical domain.

Laser sources which provide a THz beatnote in the optical domain.

This journal covers technology that operates in wavelengths ranging from radio frequency to the optical domain.

Balanced homodyne tomography is a reliable technique of reconstructing quantum states in the optical domain.

There is experimental work on orbital angular momentum multiplexing in the optical domain.

The submillimeter, or terahertz band, exists between technologies in traditional microwave radiation and optical domains.

Instead, the goal of this research was to do it entirely in the optical domain, so that high bit rates are achievable.

"You have to go from the optical domain and make an electrical replica," Dr. Mourou said.

However, a stacking technique in the optical (infrared) domain encountered technical problems which limited the number of stacked layers.
