Unidimensional time-domain quantum optics

Ultrafast Time-domain Optics

ticle provides a foundation for appreciating some of the key issues that arise in the computational aspects of ultrafast time-domain optics. Because temporal dispersion exists in all materials, it is fundamental to describing the optical field in material bodies when the field is pulsed, especially when the pulse is either ultrashort or ultrawideband. Temporal dispersion implies that the materi...

Fourier information optics for the ultrafast time domain.

Ultrafast photonic signal processing based on Fourier optics principles offers exciting possibilities to go beyond the processing speeds of electronics technologies for applications in high-speed fiber communications and ultrawideband wireless. I review our recent work on processing of ultrafast optical signals via conversion between time, space, and optical frequency (Fourier) domains. Specifi...

Perhaps Unidimensional Is Not Unidimensional

Miller (1956) identified his famous limit of 7 ± 2 items based in part on absolute identification-the ability to identify stimuli that differ on a single physical dimension, such as lines of different length. An important aspect of this limit is its independence from perceptual effects and its application across all stimulus types. Recent research, however, has identified several exceptions. We...

To Quantum Optics

The theory of quantum propagator and time–dependent integrals of motion in quantum optics is reviewed as well as the properties of Wigner function, Q– function, and coherent state representation. Propagators and wave functions of a free particle, harmonic oscillator, and the oscillator with varying frequency are studied using time–dependent linear in position and momentum integrals of motion. S...
