摘要： A wavelength-selective cross-connect (WSXC) device configured to route any set of carrier wavelengths from a corresponding input port to any selected output port. The WSXC device comprises a diffraction grating and a beam-steering device optically coupled to one another and to the input/output ports using astigmatic optics. The astigmatic optics includes one or more cylindrical lenses configured to image one beam-steering surface onto another beam-steering surface to enable a continuous spectral response. The astigmatic optics may further include (i) a cylindrical Fourier lens that enables the WSXC device to convert a change in the angular beam steering performed by the beam-steering device into a corresponding image-spot displacement at the output ports and/or (ii) one or more cylindrical lenses configured to image the active surface of the beam-steering device onto the diffraction grating. Various unfolded configurations of the various embodiments of the WSXC device are also disclosed.

摘要： An apparatus includes an all-optical transmission line having, at one wavelength, a pair of relatively orthogonal optical propagating modes whose local group velocities differ along a part of the all-optical transmission line. The all-optical transmission line is formed by a sequence of optically end-connected multi-mode fiber segments. The segments include, at least, 80% of the optical path length of the all-optical transmission line. Each segment is configured such that a differential group delay between the pair varies monotonically there along and changes by, at least, 200 pico-seconds thereon.

摘要： An optical coupler for coupling optical-pump power into a multimode fiber configured to transport an optical space-division-multiplexed (SDM) signal, the coupling being performed in a manner that enables amplification of the SDM signal in the multimode fiber via a stimulated-emission process or a stimulated Raman-scattering process. The optical coupler can be a part of an optical transmitter configured for co-directional pumping, an optical receiver configured for contra-directional pumping, or a relay station disposed within an optical communication link and configured for either type of pumping. The optical coupler can advantageously be used, e.g., to offset the different degrees of attenuation to which the SDM-signal components corresponding to different guided modes of the multimode fiber are subjected to therein.

摘要： An optical communication system having an optical transmitter and an optical receiver optically coupled via a multi-path fiber. The optical transmitter launches, into the multi-path fiber, an optical transverse-mode-multiplexed (TMM) signal having a plurality of independently modulated components by coupling each independently modulated component into a respective transverse mode of the multi-path fiber. The TMM signal undergoes inter-mode mixing in the multi-path fiber before being received by the optical receiver. The optical receiver processes the received TMM signal to reverse the effects of inter-mode mixing and recover the data carried by each of the independently modulated components.
