摘要： One embodiment of an optical fiber for reducing insertion loss and insertion loss ripple includes a tapered region where the optical fiber has a diameter of approximately 125 microns at a first end and a diameter of approximately 50 microns at a second end. The cladding layer of the tapered region is tapered from the first end towards the second end. This section of the optical fiber may be tapered using an etch process or any other technically feasible process. The tapered configuration enables the distance between the optical axes of two optical fibers inserted into a ferrule to be reduced from approximately 125 microns to approximately 50 microns. Decreasing the distance between the optical axes causes a reduction in both insertion loss and insertion loss ripple.

摘要： One embodiment of the present invention includes a plurality of first optical elements and a second optical element optically coupled to one another in cascaded fashion. Each first optical element has a group delay response characterized by a first period such that only one group delay peak occurs within a first channel. By contrast, the second optical element has a group delay response characterized by a second period, which is less than the first period, such that more than one group delay peak occurs within the first channel. The preferred embodiment uses cascaded GT etalons to provide the desired group delay responses. One advantage of the present invention is that the passband of the dispersion compensator is increased relative to prior art designs without increasing insertion losses. Alternatively, the same passband common in prior art designs may be achieved with fewer GT etalons, thereby reducing insertion losses.

摘要翻译：本发明的一个实施例包括多个第一光学元件和以级联方式彼此光学耦合的第二光学元件。每个第一光学元件具有组延迟响应，其特征在于第一周期，使得在第一通道内仅出现一个组延迟峰值。相反，第二光学元件具有特征在于第二周期的群延迟响应，该第二周期小于第一周期，使得在第一信道内发生多于一个群延迟峰值。优选实施例使用级联的GT标准具来提供期望的组延迟响应。本发明的一个优点是，相对于现有技术的设计，色散补偿器的通带增加，而不增加插入损耗。或者，可以用较少的GT标准具实现现有技术设计中通用的相同通带，从而减少插入损耗。

摘要： A system for a re-configurable optical de-multiplexer, multiplexer or add/drop multiplexer is provided. A re-configurable de-multiplexer system comprises a wavelength selective switch having an input port, an output port and an internal port; a wavelength division de-multiplexer (WDM) optically coupled to the internal port and a plurality of dropped-channel ports optically coupled to the WDM. The wavelength selective switch receives a plurality of input wavelength-division multiplexed channels from the input port and routes a first subset of the channels to the output port and a second subset of channels to the internal port and then to the WDM. The WDM separates each of the dropped channels to a different respective one of the channel ports.
