摘要： An integrated Mach-Zehnder optical light intensity modulator (1) comprises at least one input (3) two outputs (5a, 5b), and first (7) and second (9) optical paths extending between and optically coupled to the input and outputs, each optical path including a phase modulator (15a, 15b), the light intensity modulator being arranged such that, with no phase modulator actuated, for a particular known wavelength of light there is a π/2 radians, or integer multiple of π/2 radians, phase difference between the optical paths for light of that wavelength propagating from the input to the outputs, thereby causing the light to be emitted from each output with substantially equal intensity. Actuation of the phase modulator of only one of the optical paths such that no more than a π/2 radians phase shift is thereby imposed on the light propagating along that path causes up to 100% of the light emitted by the light intensity modulator to be emitted from one of the outputs, and subsequent actuation of the phase modulator of the other optical path only, such that no more than a π/2 radians phase shift is thereby imposed on the light propagating along that path causes up to 100% of the light emitted by the light intensity modulator to be emitted from the other output.

摘要： A high speed optical switch may include a plurality of pairs each having a length L π that may be connected in series. All switching may be accomplished in the high speed optical switch by discharging one arm in a pair (e.g. a single L π ) at a time. L π may refer to a guide length used to induce a relative π phase shift. Each of the plurality of pairs may have two arms with both arms being initially charged. If both arms in any give pair have the same state, (e.g. either charged, uncharged, or charging) a "1" may be transmitted through that pair. If the arms are in opposite states, (e.g. charged or uncharged) a π phase shift may be produced and a "0" may be transmitted through that pair. For example, a first pair in the series may be recharged while other pairs are using in switching.

摘要： A guided wave optical switch having a passive optical component optically coupled to a low gain optical amplifier - both being formed monolithically in a semiconductor substrate. The passive optical component may comprise a single-mode -3 dB optical power splitter that receives at an input an optical signal and splits that optical signal approximately equally between two outputs. The passive optical component may also comprise an optical isolator, an optical circulator, and other known passive optical devices. The low gain optical amplifier includes a waveguide having an active region that may provide optical signal gain when excited by an electrical current provided by a metal or metallic electrode connected to the active region. The active region may be a bulk active region, a multiple quantum well active region, or the waveguide may comprise a buried heterojunction waveguide having either a bulk or multiple quantum well active region.

摘要： A process for manufacturing a semiconductor optical part in which a ridge type semiconductor optical amplifier section and a ridge type semiconductor optical waveguide connected to the optical amplifier section are integrally formed on a single substrate. The semiconductor optical amplifier section has a path width narrower than that of the semiconductor optical waveguide. The current density of the semiconductor optical part thus manufactured can be high since the injected current in the semiconductor optical amplifier can be much constricted. Therefore, optical amplification of a high efficiency can be performed even in the case of a small injected current, and the semiconductor optical part is useful as an optical amplifier of a high efficiency.

摘要： Monitoring output power levels of a carrier-effect based switching cell allows phase errors resulting from driving a PIN or PN junction of the switching cell to be dynamically compensated for. The compensation may also allow for compensating of phase errors resulting from the phase imbalance of input couplers as well as phase errors from the waveguide due to fabrication variations. By dynamically compensating for phase errors caused by the driving of the PIN or PN junction, the extinction ratio of the carrier-effect based switching cell can be increased.

摘要： A photonic processing module (100) comprises a high index-contrast waveguide device comprising a substrate (102), a first layer (104) disposed on the substrate having a first refractive index, and a relatively thin second layer (106) disposed on the first layer. The second layer has a second refractive index providing a high index-contrast with the first layer, and the device includes at least one thin-ridge waveguide element (108) formed in the second layer which supports a guided mode in a longitudinal direction. An optical input port (110) is configured to direct an input beam into a slab mode of the second layer, the beam being directed to propagate at a predetermined angle θ to the longitudinal direction of the thin-ridge waveguide element. The angle θ is associated with a resonant coupling between the slab mode of the second layer and the guided mode of the thin-ridge waveguide element. An output beam is thus generated when the input beam includes one or more optical components corresponding with the resonant coupling. An optical output port (112) is configured to receive the output beam.

摘要： Le guide optique étant composé de couches de semi-conducteurs formant au moins une double hétéro-structure (21, 22, 23, 24), la variation d'indice se fait par injection d'électrons. Cette injection est provoquée par une tension électrique appliquée sur un contact de type Schottky (26, 27) déposé sur la double hétéro-structure. Un commutateur selon l'invention utilise la variation d'indice optique qui induit un effet miroir, la commutation étant effectuée par réflexion de l'onde optique sur une zone d'indice optique réduit. L'invention s'applique notamment pour des commutations d'ondes optiques ultra-rapides à faible pertes d'insertion.
摘要翻译：由于光波导由形成至少一个双异质结构（21,22,23,24）的半导体层构成，因此可以通过注入电子来实现折射率变化。通过向沉积在双异质结构上的肖特基接触（26,27）施加电压而产生这种注入。根据本发明的开关使用光学折射率的变化，其产生镜面效应，用于通过光波在较低光学折射率的区域上的反射而发生切换。本发明特别适用于具有低插入损耗的超快速光波切换。
