摘要： A method of making an optical fiber article can include providing an optical fiber including a least a core; providing a preform; and subsequent to the foregoing providing of the optical fiber and the preform, drawing the preform so as to dispose a region about the optical fiber. An optical fiber article can include a core; a pump cladding disposed about the core, the pump cladding for propagating pump light; and a second cladding disposed about the pump cladding, where the second cladding can provide a photonic bandgap for tending to confine pump light to a region about which the second cladding is disposed. The second cladding can comprise a plurality of layers including a first layer having a different optical property than a second layer, and the plurality of layers can be arranged as to provide the photonic bandgap effect.

摘要： A multiplexer circuit (100) has at least two input channels (IN0, IN1) and an output channel (2). Each input channel (IN0, IN1) has a first transmission gate (FT0, FT1) and a second transmission gate (ST0, ST1). The transmission gate can be switched by a select signal (SELECT0, SELECT0; SELECT1, SELECT1) for connecting the input channel (IN0, IN1) to the output channel (2). At least one of the input channels (IN0, IN1) has a bypass circuit for preventing a current flowing through the first transmission gate (FT0, FT1) from reaching the other input channel.
