    Abstract: An optical communications system includes a laser transmitter to generate an optical signal and a first optical fiber network coupled to transmit the optical signal from the laser transmitter system. A first latchable, asymmetric coupler is disposed along the first optical fiber network to receive the optical signal, and has a first tap output that receives a selected and alterable first fraction of the optical signal. A second latchable, asymmetric coupler is disposed along the first optical fiber network to receive the optical signal from the first latchable asymmetric coupler and has a second tap output that receives a selected and alterable second fraction of the optical signal incident at the second latchable. In certain embodiments the first and second couplers are capable of operating at any of at least three tapping fractions.

    Abstract: Optical wavelength division multiplexing (WDM) devices include an optical chip having a number of waveguides therein, with a common optical fiber and single wavelength channel optical fibers optically coupled to the waveguides. Wavelength sensitive filters are disposed between the chip and the fibers, or across waveguides within the chip to reflect light at certain wavelengths and to transmit light at other wavelengths. In sonic embodiments, all of the fibers are located at the same end of the chip, in others the common fiber is located at one side of the chip and the single channel fibers located at another side, while in others the common fiber is located at a first side of the chip and the single channel fibers are located either at the first side of the chip or at a second side of the chip.

    Abstract: Integrated WDM mux/demux devices are disclosed. Some embodiments are directed to an in-line WDM mux/demux device formed with a substrate and a common port at a first side of the substrate and a plurality of separated wavelength ports at a second side of the substrate. The first side of the substrate is free of separated wavelength ports. Other embodiments are directed to a WDM mux/demux device in which a linear variable filter is disposed in the substrate for separating the signals in different channels. In other embodiments, the filter or filters are sandwiched between the edges of adjacent substrates, such that light propagating along a waveguide in one of the substrates is transmitted through the filter to a waveguide in the second substrate. The adjacent substrates may be mounted to a base substrate.
