Abstract: An optical filter apparatus for processing an optical signal comprising a spectrum broadening device for spectrally dividing one or more channels of the optical signal into a discrete set of spectral components for each channel, a collector for collecting the spectral components on a discrete number of corresponding light channels, one or more processors for individually processing one or more of the spectral components on the light channels, and a combiner for recombining the spectral components on the light channels.

Abstract: A broadband wavelength-division multiplexer comprises two input waveguides for two input signals, each of which is from a different waveleng th band, a multi-mode interference waveguide for producing an output wavelength-division multiplexed (WDM) signal comprising the two input signal s where at least one of the two input signals is partially coupled to produce the output WDM signal, and an output waveguide for providing the output WDM signal. Optionally, at least another output waveguide can be used to trap all or some power not coupled t o produce the output WDM signal.

Abstract: A wavelength converter with a monolithically integrated delay loop in a delayed interference configuration that needs only one SOA or other non-linear optical element coupled to the input fiber, a first coupler to arranged to split the output of the SOA or other non-linear optical amplifying element into two paths having controllable delay and phase shift characteristics, and at least one output coupler to combine the signals present on the two paths to provide the converter output. Unlike piror-art hybrid wavelength converters, one embodiment of the invention has a monolithically integrated delay loop utilizing an asymmetryc coupler that can be either the first coupelr or the second coupler, or both. Another embodiment of the invention has a coupler that does not require an asymmetric splitting ratio, and has either a gain element in one of the paths, an attenuation element in one of the paths, or both. If desired, yet another coupler can be added to the wavelength converter to couple out part of the light in one of the paths, thereby obtaining a better extinction ratio.

Abstract translation: 一种波长转换器，其具有在延迟干扰配置中的单片集成延迟环路，其仅需要耦合到输入光纤的一个SOA或其它非线性光学元件，第一耦合器被布置成将SOA的输出或其他非线性光学 放大元件分成具有可控延迟和相移特性的两条路径，以及至少一个输出耦合器，以组合存在于两条路径上的信号以提供转换器输出。 与非专利文献混合波长转换器不同，本发明的一个实施例具有使用可以是第一耦合器或第二耦合器或两者的不对称耦合器的单片集成延迟环。 本发明的另一个实施例具有不需要不对称分裂比的耦合器，并且在一条路径中具有增益元件，在一条路径中的衰减元件或两者之中。 如果需要，可以将另一个耦合器添加到波长转换器中以将其中一条路径中的一部分光耦合，从而获得更好的消光比。
