Note on self-phase modulation and cross-phase modulation
Optics Communications, 1995Abstract It is investigated to what extent self-phase modulation and cross-phase modulation operate when a single badly mode locked laser pulse travels in a nonlinear medium. We restrict our investigation of intensity induced phase effects to those that can be measured with stationary interference patterns.

The phase-modulated logistic map
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2005We study the logistic mapping with the nonlinearity parameter varied through a delayed feedback mechanism. This history dependent modulation through a phaselike variable offers an enhanced possibility for stabilization of periodic dynamics. Study of the system as a function of nonlinearity and modulation parameters reveals new phenomena: In addition to

Birefringence modulation in fiber-optic phase modulators
Optics Letters, 1994We report an unusually large birefringence modulation in fiber-optic phase modulators formed with cylindrical piezoelectric transducers when driven at a few hundred kilohertz. The magnitude of the birefringence modulation is a strong function of modulation frequency.

Photoelastic modulator: polarization modulation and phase modulation
Journal of Optics, 1995Photoelastic modulators are studied here as both birefringence (or polarization) and phase modulators. In the first part of this work we have determined the influences of time dependent variations of index and thickness, for an ideal modulator where oscillation is supposed to be perfectly longitudinal.

A Modulated Helical Nanofilament Phase
Angewandte Chemie, 2013The modern study of the liquid crystal (LC) phases formed by bent-core molecules has led to many interesting and unexpected phenomena, including the first example of spontaneous reflection symmetry breaking and conglomerate formation in a bulk fluid phase.

Computational Phase-Modulated Eyeglasses
IEEE Transactions on Visualization and Computer Graphics, 2021We present computational phase-modulated eyeglasses, a see-through optical system that modulates the view of the user using phase-only spatial light modulators (PSLM). A PSLM is a programmable reflective device that can selectively retardate, or delay, the incoming light rays. As a result, a PSLM works as a computational dynamic lens device.
