In this paper, we propose an application of the mutually pumped phase conjugation to the all-
optical connection switch and present the two type of the bi-directional cross connector with …

Je suis reconnaissante à Gérald Roosen, mon directeur de thèse, de m'avoir accueilli dans
son groupe de recherche et pour son soutien dans les moments de doute. Je pcnse avoir …

Ultrasonic excitation of a solid sample (optically opaque) can be detected by directing a
laser beam at one of its surfaces. Surface motion causes a transient phase shift upon the …

Mutually-pumped phase conjugation in BaTiO 3 crystal with two coherent incident beams
has been studied experimentally for the bridge configuration. We observed that when the …

A statistical approach for the derivation of the phase conjugation dynamics is presented. For
the optical scheme of the Double Phase Conjugate Mirror (DPCM) using Bi 12 TiO 20 (BTO) …

We present the insertion of a Double Phase Conjugate Mirror (DPCM) in a Fiber-Optic
Gyroscope (FOG). This double phase conjugate mirror is inserted in the middle of the fiber …

This thesis describes and assesses experimentally novel configurations for various types of
phase conjugation in the barium titanate crystals and novel designs for optical resonant …

Summary form only given. Some of the novel quantified characteristics for double phase
conjugate mirrors are analysed including the effects of the nonlinearity on the critical …

The temporal evolution of double phase-conjugate mirrors (DPCM's) in photorefractive
materials such as BaTiO_3: Co: Fe is studied by use of the plane-wave expansion method …

This report covers the development, test and evaluation of an adaptive phased array optical
processor. This system is designed to optimally process the wide band signals from large …
