| 161 | All-optical wavelength coded logic gates | US965851 | 1997-11-07 | US6151428A | 2000-11-21 | Kerry John Vahala; Roberto Paiella; Guido Hunziker |
| All-optical logic gates in which binary words are encoded using wavelength. A method and apparatus for processing information in this wavelength encoded format is provided. The processing may occur entirely in the optical domain. This approach is modular and enables construction of logic gates using custom wave guide chips that can be mass-produced in a manner similar to that of conventional electronic digital chips. Specific gates, such as AND, OR, EXOR, or NAND, may be "programmed" into a given chip during its fabrication to encode the desired truth table. The output states of the chip are determined by ultrafast mixing of binary encoded wavelengths in a semiconductor optical amplifier. The result is a new wavelength having a relationship to the input wavelengths determined entirely by the desired truth table. The possible clock-rates for these gates can be exceedingly high, such as several hundred Gigabits/second. The product of integer word length "N" and gate clock speed can exceed several Terabits/second and may be as high as the overall optical bandwidth of the system. Complicated multi-input functions may be constructed using this approach and dynamically programmable functions may be built in which either electrical or optical signals reconfigure a set of gates by reprogramming the inverter operations in the chips. | ||||||

| An optically controlled optical switch operating at a high speed and at a high efficiency can be realized with a simple construction. An optical signal exiting from a nonlinear optical waveguide is passed through an optical frequency filter and then guided into an optical output signal port. The optical frequency filter is a band-pass filter for passing only optical signal pulses having a center frequency of .omega.1. Where the center frequency .omega.0 of controlling light is set within the absorption region of the nonlinear optical waveguide, optical controlling pulses are absorbed, and carriers are excited. This results in a change in the refractive index. Consequently, the center frequency .omega.1 of only the optical signal pulses entered simultaneously with the optical controlling pulses is shifted to .omega.2. The optical frequency filter blocks optical signal pulses whose center frequency has been shifted to .omega.2. Thus, a gate-type optical switching action is accomplished. | ||||||

| The invention relates to wavelength converters for optical signals, as used in telecommunications, in particular for routing signals. The invention relates in particular to a wavelength converter including an interferometer structure for delivering an output optical signal, in which converter first and second branches, including at least one first semiconductor optical amplifier, are coupled to input peripheral semiconductor optical amplifiers and/or to an output peripheral semiconductor optical amplifier, wherein the structure of the active waveguide of at least one peripheral amplifier is so designed that it has a ratio of active area to confinement factor greater than that of the active waveguide of said first amplifier. | ||||||

| 165 | Device for and method of modifying the spectral characteristics of optical signals | US690068 | 1996-07-31 | US5754334A | 1998-05-19 | Massimo Artiglia; Ernesto Ciaramella |
| The modification is accomplished on the basis of the solution known as spectral inversion (or optical phase conjugation). The device (1) comprises a medium, such as typically a dispersion shifted optical fiber (4), into which the signal to be modified is injected together with a pump signal at such a level as to induce modulation instability in the fiber (4). At the output of fiber (4) a spectrally inverted optical signal is available, which signal is translated in wavelength and is obtained with high conversion efficiency. Preferably, in order to avoid stimulated Brillouin scattering, the pump signal is subjected to spectrum broadening, for instance by means of a modulator (5). | ||||||

| A tapered optical fiber component is provided that has an optical fiber with a cladded region. An optical core passes through the cladded region. The cladded region has a tapered extended first region drawn down in diameter to form an effective area region that has a predetermined effective area. The tapered extended first region is formed to adiabatically concentrate an optical signal for propagation through the effective area region of reduced diameter. The power density of the optical signal propagating through the effective area region is increased as an inverse function of the effective area. | ||||||
