Variable dispersion step-phase interferometers |
摘要 |
Optical interferometers with variable dispersion are shown. These interferometers are useful as optical interleavers and through the control of their design, are made to have negative and near-zero dispersion. The N-type interleaver has a negative dispersion slope near the center of the pass band. The Z-type interleaver has a dispersion that is close to zero within the pass band. These interleavers can be arranged in various systems to produce low dispersion optical networks. The non-linear phase etalons in the N- and Z-type interleavers taught herein contribute to the device dispersion. The N-Type interleaver includes a linear cavity length that is 1.5 times that of a non-linear cavity. The Z-type interleaver includes two non-linear cavities that are out of phase with each other such that the net dispersion is close to zero.
