“…To overcome these problems we have studied all-optical bistable switching devices by combining a distributed feedback (DFB) structure and an intensitydependent refractive index change in a compound semiconductor, GaInAsP. 3) Bistable and threshold operation, 4,5) Boolean AND-logic operation 6) and polarization-independent switching operation 7) have been investigated using a GaInAsP/InP DFB waveguide structure. However, the magnitude and response speed of the intensity-dependent index change have not been measured in GaInAsP waveguides below the band-gap yet.…”

From picosecond pump-probe and interferometric experiments, we measured the intensity-dependent absorption and refractive index changes of GaInAsP/InP waveguides whose band-gap wavelengths ranged from 1.2 to 1.41 µm. An optical loop mirror interferometer was employed to measure the refractive index change in a time domain. The temporal response of the probe in GaInAsP waveguides was shown to be instantaneous following 4 ps pump pulses. The intensity-dependent refractive index coefficient was measured to be from -0.55 ×10-12 to -3.37 ×10-12 cm2/W. Also, intensity-dependent absorption changes were compared for three types of waveguide.

We investigated the direct measurement of intensity-dependent refractive index changes in GaInAsP/InP ridge waveguides with ps-order pump pulses below the band gap using an optical loop mirror interferometer. The temporal response of the probe in GaInAsP ( g ¼ 1410 nm) waveguides was shown to be instantaneous with respect to 4 ps pump pulses. The intensitydependent refractive index coefficient was measured to be À2:0 AE 0:6 Â 10 À12 cm 2 /W. In addition, pump-induced absorption changes were studied.

“…The awaited advantages of all-optical principles use in logical devices for optical computing, optical associative memories, and optical interconnections are connected with their higher operation frequencies in signal processing, small energy losses and practically unlimited possibilities to organize parallel operating the signals [1][2][3][4][5]. The all-optical ideology is used to mean the absence of electronic transforming signals at any stage of the process as well as spin or phonon mechanisms in signal processing.…”

We propose the principal scheme of all-optical adder based on the dependence of electromagnetic spectra in photonic bandgap materials containing optically nonlinear layers on the light signal intensity. The system consisting of periodical layered structure covered by optically nonlinear material is investigated and photonic structure behavior with changing intensity is calculated. Theoretical estimations of adder parameters are made for different nonlinear materials and frequencies of laser source.
