摘要： An adjustable optical signal delay module which adjusts power of an amplified spontaneous emission generated by a semiconductor optical amplifier and feeds the adjusted amplified spontaneous emission back to the semiconductor optical amplifier in a direction opposite to an optical signal being amplified by the semiconductor optical amplifier is provided. The feedback of the adjusted amplified spontaneous emission varies a group refractive index of the semiconductor optical amplifier and delays the transmission of an optical signal through the semiconductor optical amplifier. By that arrangement, the adjustable optical delay module obviates the need for the pump laser conventionally required by a coherent population oscillation mechanism. The feedback optical loop includes a variable optical attenuator, an optical filter, and optical circulators. A user can control the delay timing of optical signals via adjusting optical power in the feedback optical loop.

摘要： Interleaver/deinterleavers for combining/separating optical channels. An interleaver/deinterleaver is “folded” when an optical signal follows an optical path that passes through a birefringent element multiple times. Double-pass refers to optical signals following a (folded) path through the birefringent element twice. Multi-pass refers to optical signals following a (folded) path through the birefringent element multiple times. When operating as a deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g., WDM signal) into subsets of optical signals (e.g., even and odd ITU channels). When operating as an interleaver, the interleaver/deinterleaver mixes subsets of optical signals into a multiplexed optical signal. The interleaver/deinterleaver can be used to increase the bandwidth of an optical network. For example, the interleaver/deinterleaver can be used to interface components designed for a first channel spacing (e.g., 100 GHz) to components designed for a second channel spacing (e.g., 200 GHz). Folded interleaver/deinterleavers cause dispersion because the speed at which the ordinary beam of an optical signal passes through the birefringent element is different that the speed at which the extraordinary beam of the optical signal passes through the birefringent element. In order to reduce or eliminate dispersion, the polarization of the optical signal is reversed for alternating passes through the birefringent crystal. For example, if a signal is horizontally polarized for a first pass through the birefringent crystal, the signal is rotated to be vertically polarized for a second pass through the birefringent crystal. For a third pass through the birefringent element, the signal is rotated to be horizontally polarized.

摘要翻译： 用于组合/分离光通道的交织器/去交织器。 当光信号跟随穿过双折射元件的光路多次时，交织器/解交织器被“折叠”。 双通道是指通过双折射元件的（折叠）路径之后的光信号两次。 多通道是指多次通过双折射元件的（折叠）路径之后的光信号。 当作为解交织器操作时，交织器/去交织器将光信号（例如，WDM信号）分离成光信号（例如偶数和奇数ITU信道）的子集。 当作为交织器操作时，交织器/解交织器将光信号的子集合成复用的光信号。 交织器/去交织器可以用于增加光网络的带宽。 例如，交织器/解交织器可以用于将为第一信道间隔（例如，100GHz）设计的组件接口设计成用于第二信道间隔（例如，200GHz）的组件。 由于光信号的普通光束通过双折射元件的速度与光信号的非寻常光束通过双折射元件的速度不同，所以折叠的交织器/解交织器引起色散。 为了减少或消除色散，对于交替穿过双折射晶体，光信号的偏振反转。 例如，如果信号被水平极化以进行通过双折射晶体的第一次通过，则信号被旋转以被垂直偏振，以进行双折射晶体的第二次通过。 对于通过双折射元件的第三遍，信号被旋转以进行水平极化。
