摘要： The invention relates to a device and a method for switching optical wavelength channels. Said optical wavelength channels are introduced into at least one access waveguide provided on a first side of a first multi-mode waveguide (10). Subsequently, the wavelength channels are transmitted through said multi-mode waveguide (10) and projected on at least two connection waveguides provided on the opposite side. Subsequently, the optical wavelength channels are transmitted through the connection waveguides. For each wavelength selective cross-connection structure (2, 4, 6, 8) the phase is changed for a reflecting wavelength of two phase control elements (C1, C2, D1, D2, E1, E2, F1, F2) arranged in a first and a second connection waveguide on a first side of said wavelength selective cross-connection structure (2, 4, 6, 8), simultaneously as at a second side of said wavelength selective cross-connection structure (2, 4, 6, 8) said reflecting wavelength phase remains relatively unchanged. For each wavelength selective cross-connection structure (2, 4, 6, 8) the phase is changed for transmitting wavelengths once in a first and a second direction per wavelength selective cross-connection structure (2, 4, 6, 8). The phase difference between the optical signal in each access waveguide provided on the first side of the second multi-mode waveguide (20) determines where the optical signal is focused on the opposite side.

摘要： The present invention concerns a multi-wavelength selective switch in the form of a directional coupler structure. The directional coupler structure comprises two waveguides, wherein the waveguides arranged exhibit different effective diffractive index. The waveguides in one section are arranged in the proximity of each other, such that an optical field in the first waveguide can overlap a second waveguide and vice versa and that in said section at least two gratings are arranged for co-directional coupling. Said gratings are arranged isolated from each other. The invention further comprises a method for switching of wavelength channels through the use of said multi-wavelength selective switch.

摘要： The present invention proposes a method and a device to add and drop optical channels in an optical transmission system (1) in which a multi-channel optical signal is transmitted into an optical fiber line (300). The OADM (Optical Add/Drop Multiplexer) device (695; 695') includes an optical splitter (673) receiving an input signal which includes at least one sub-group of the whole channels. Optical splitter (673) has an unbalanced power splitting ratio - in the range 60:40 to 90:10 - for feeding a main power fraction (60 % to 90 %) of said input signal to a first output port and a secondary power fraction (40 % to 10 %) of said input signal to a second output port. The secondary power fraction defines a drop signal and is received by a demultiplexer (680; 682) where drop channels are extracted. The main power fraction defines a pass-through signal which is conveyed from the optical splitter (673) to an optical coupler (674) where the pass-through signal is coupled with an add signal, coming from a multiplexer (681). Optical coupler (674) has an unbalanced coupling ratio - in the range 60:40 to 90:10 - so that it generates an output signal prevalently constituted by the pass-through signal. Cascaded Bragg gratings (678), positioned between the optical splitter (673) and the optical coupler (674), selectively retro-reflect the drop channels from the pass-through signal, and an optical isolator (679), positioned before the optical splitter (673), suppresses the retro-reflected drop channels.

摘要： A switchable wavelength router switches wavelength division multiplexed (WDM) optical signals between N input ports (101, 102) and M output ports (103, 104, 105). Each WDM signal is spatially decomposed into N pairs of orthogonally polarized beams by a polarization-dependent routing element, such as a birefringent element (201). A polarization rotator array (204) rotates the polarization of each beam pair so that both beams in each pair have the same polarization. A wavelength filter (206) then demultiplexes each beam pair to create N sets of four beams. A second polarization-dependent routing element (202) spatially routes the four beams in each of the N sets based on their polarizations, and also spatially combines selected beam pairs from different sets to produce M pairs of beams. A second polarization rotator array (205) restores each beam pair to orthogonal polarization, and a final polarization-dependent routing element (203) recombines each beam pair to produce M output beams at the output ports (103, 104, 105).

摘要： The invention concerns a communication device interface which is used for optional connection of input lines (E1, ..., E128) assembled to form a plurality of input line groups to at least one output line group (A1, ..., A16), each of the input line groups being connected to a separate interface element (SE) of at least one interface element arrangement (e.g. KA21) with a funnel structure. Each interface element arrangement further comprises a number of outputs corresponding to the number of output lines belonging to the respective output line group. Each of these outputs is connected to one of the output lines belonging to the respective output line group. According to the invention, the respective interface element arrangement (KA21) consists simply of the interface elements (SE) connected to the input line groups. Each of the interface elements has outputs which are individually associated with the output lines belonging to the respective output line group. Only one of the mutually corresponding outputs of these interface elements can thus be optionally connected by switching means to the relevant output line of the respective output line group.
