摘要： A novel semiconductor optical amplifier (SOA) can operate as an optical inverter as well as a power-restoring device. Together, an optical-OR and the optical inverter can provide a wide variety of high speed optical logic gates and functions. The optical inverter uses cross-gain modulation (XGM) to invert a modulated signal on a first input, to produce an inverted output. The inverse of the modulation is transferred from a first wavelength of the modulated first input to a second wavelength of a continuous-wave second input. A filter can then block the first wavelength, allowing the inversely-modulated second wavelength to be output as the inverted output. The first and second wavelengths are swapped in alternate inverters in a logic path. The Y-junction can be implemented as a Multi-Mode Interference (MMI) device.

摘要： Optical logic gates are constructed from Mach-Zehnder Interferometer (MZI) optical circuits. A multi-mode interference (MMI) splitter divides a continuous-wave input into two branches of the interferometer. Each branch has a semiconductor optical amplifier (SOA). When a logic input having a logic-high power level is applied to one of the SOA's, cross-phase modulation occurs in the SOA. The phase shift increases through the SOA. The branch coupled to the logic input has a relative phase shift of &pgr; compared with the other branch. When two branches with the &pgr; phase difference are combined, destructive interference occurs, producing a logic low. An MMI combiner or an equivalent phase shifter is used to combine the two branches. The MMI splitter adds a phase shift of &pgr;/2 to the upper branch but not to the lower branch, while the MMI combiner also adds &pgr;/2 shifts.
摘要翻译：光逻辑门由Mach-Zehnder干涉仪（MZI）光电路构成。多模干扰（MMI）分离器将连续波输入分成干涉仪的两个分支。每个分支都有一个半导体光放大器（SOA）。当具有逻辑高功率电平的逻辑输入被应用于SOA中的一个时，在SOA中发生交叉相位调制。相移通过SOA增加。耦合到逻辑输入的分支与其他分支相比具有pi的相对相移。当具有pi相位差的两个分支组合时，发生相消干扰，产生逻辑低电平。使用MMI组合器或等效移相器来组合两个分支。 MMI分路器将pi / 2的相移添加到上分支，但不分配给下分支，而MMI组合器也增加pi / 2移位。
