摘要： A measurement of nonlinear refractive index coefficient of an optical fiber with a Sagnac interferometer, comprises the steps of employing the optical fiber in a Sagnac interferometer, splitting a signal beam into two signals, launching the two split signals into the interferometer in opposite directions, combining and detecting the signals counter-propagated in the interferometer, and detecting the refractive index coefficient of the optical fiber in accordance with the difference between the two signal powers determined by a control beam. The quasi-static phase shift of the signal beam counter-propagating the same paths of the interferometer is induced by rotating the optical fiber loop of the interferometer. The present invention gives rise to little error because it does not require precise information about the pulse width of a used beam or a high-power light.

摘要： An all-optical signal processing apparatus of a non-linear fiber loop mirror type comprises a very high-speed all-optical switch that can be used as a reverse multiplexed switch in a high-speed time division optical communication. The apparatus includes a non-linear loop mirror for switching signal light by adjusting light using the non-linear effect of an optical fiber and the characteristics of a sagnac interferometer as the fundamental configuration. The all-optical switch is constructed so that another adjustment light having an appropriate time delay with respect to an existing adjusting light is additionally introduced in order to compensate for the limitation on the switching bandwidth imposed by the walk-off between adjusting and signal lights in a conventional non-linear optical fiber loop mirror. This compensates for the cross-talk of the noise signals due to DC components generated in the conventional apparatus. A switching window of a desirable size is obtained by properly adjusting the time delay between two adjusting lights and resolving the bandwidth limitation of the switch due to the walk-off of the adjusting and signal lights according to the timing jitter of signal light.

摘要： A vertical modulator with a dual mode distributed Bragg reflection (DBR), includes a pair of integrated elements using different wavelengths to provide functions of logical operation, data switching and wavelength conversion. The optical device includes a first optical structure operating at a first wavelength (.lambda..sub.1) and a second optical structure operating at a second wavelength (.lambda..sub.2). The first and second optical structures are formed over a semiconductor substrate. The first optical structure, which operates at the first wavelength (.lambda..sub.1), transmits its data to the second optical structure so that data corresponding to the second wavelength (.lambda..sub.2) can be output. Since the wavelength of input light is different from the wavelength of output light, the optical device serves as a modulator which performs a logic operation and switching function while carrying out wavelength conversion.

摘要： A surface adsorption apparatus for dissociating H.sub.2 molecules into atomic hydrogen in a vacuum vessel and adsorbing the atomic hydrogen on a sample surface is disclosed. A vacuum tube is mounted in the vacuum vessel. A nozzle is connected to the vacuum tube having a plurality of bent portions. A heating member receives electrical power from a power supply source and heats the nozzle to a predetermined temperature. A heat shielding member is located in a path of the atomic hydrogen between one end of the nozzle and the sample surface for shielding the sample surface from heat radiating from the nozzle. The H.sub.2 molecules collide with inner wall surfaces of the bent portions to be readily dissociate into the atomic hydrogen. The atomic dissociated hydrogen propagates toward the sample surface and is adsorbed on the sample surface. Since the nozzle comprises bent portions, H.sub.2 molecules frequently collide with inner wall surfaces of the nozzle to readily dissociate into atomic hydrogen. The H.sub.2 collision efficiency is significantly improved by increased surface collisions with the bent portions. Because the bent portions of the nozzle are heated by the heating member, the construction of the apparatus is simplified.
