摘要： A wavelength router that selectively directs spectral bands between an input port and a set of output ports. The router includes a free-space optical train disposed between the input ports and said output ports, and a routing mechanism. The free-space optical train can include air-spaced elements or can be of generally monolithic construction. The optical train includes a dispersive element such as a diffraction grating, and is configured so that the light from the input port encounters the dispersive element twice before reaching any of the output ports. The routing mechanism includes one or more routing elements and cooperates with the other elements in the optical train to provide optical paths that couple desired subsets of the spectral bands to desired output ports. The routing elements are disposed to intercept the different spectral bands after they have been spatially separated by their first encounter with the dispersive element.

摘要： A method of monitoring input light having a plurality of spectral bands (wavelength channels) includes the following, carried out for at least two different spectral bands at different times, using a common photodetector and wavelength-monitoring circuit that is coupled to the photodetector: separating one of the spectral bands from the plurality of spectral bands, directing light in only that spectral band to the photodetector, and generating, with the wavelength-monitoring circuit, a signal representing a quality characteristic of a modulated or unmodulated pattern of light in that spectral band. Each of the plurality of spectral bands can be individually and sequentially monitored in round-robin fashion, each of a subset of the spectral bands can be individually and sequentially monitored in round-robin fashion (to provide selective wavelength monitoring), or the monitoring can be ad hoc in response to external requirements. If desired, the opitcal power of the plurality of spectral bands can be monitored by directing the light in the spectral bands other than the band that has been separated from the plurality to an additional common photodetector and a common power-monitoring circuit.
摘要翻译：监测具有多个光谱带（波长信道）的输入光的方法包括以下步骤：使用耦合到光电检测器的公共光电检测器和波长监测电路在不同时间对至少两个不同的光谱带进行分离：分离来自多个光谱带的光谱带之一，仅将光谱带入光电检测器，并且利用波长监视电路产生表示在该光谱中的调制或未调制模式的质量特性的信号带。可以以循环方式单独和顺序地监视多个频谱带中的每一个，可以以循环方式（以提供选择性波长监视）单独和顺序地监视频谱带的子集中的每一个，或者监视可以根据外部要求进行特设。如果需要，可以通过将除了从多个分离的频带之外的频谱带引导到另外的公共光电检测器和公共功率监视电路来监视多个频谱带的操作功率。

摘要： An optical switch comprises a two-dimensional array of optical inputs, a Fourier transform lens, and a two-dimensional array of optical outputs. Each of the optical inputs emits an optical beam that is transmitted through the Fourier transform lens to one of the optical outputs. A first deflection means gives each of the optical beams a respective direction of incidence upon the Fourier transform lens. The optical output to which a given beam travels depends on the beam's respective direction of incidence. A second deflection means deflects the optical beams after they have been transmitted through the Fourier transform lens and renders the beams parallel, thereby enabling the beams to couple efficiently to the optical outputs. Each of the deflection means preferably comprises at least one Micro-Electro-Mechanical Systems, or MEMS, deflector array. The optical inputs and outputs preferably comprise optical fibers. The Fourier transform lens overcomes diffraction limitations, since the lens causes the spreading optical beams to reconverge.
