  • Method of making sequential coupler arrangements and resulting devices
    Patent number: 6839490
    Abstract: A monolithic sequential coupling arrangement has two or more fused biconic couplers joined with one common optical fiber which is not spliced. The couplers are close together in a space-saving relationship exhibiting a relatively low polarization dependent loss. The non-fused fiber portions in the arrangement have each at least one adiabatic taper.
    Type: Grant

    Date of Patent: January 4, 2005
    Assignee: JDS Uniphase Corporation

  • Ultrafast laser with multiply-folded resonant cavity
    Patent number: 6055261
    Abstract: An ultrafast laser providing short output pulses having a pulse length in the femtosecond range includes a resonant cavity including a plurality folding mirrors for folding the resonant cavity to shorten its overall length. The fold-mirrors each include a plurality of layers deposited by ion-beam sputtering onto a substrate having a surface roughness of less than about 0.5 nanometers RMS. One or more of the folding mirrors may have a negative-group-velocity-dispersion mirror for allowing the laser to operate in a pulsed mode with pulses having a length of less than 500 femtoseconds.
