Optical amplifier exhibiting net phase-mismatch selected to at least partially reduce gain-induced phase-matching during operation and method of operation
| DWPI Title: Optical amplifier structure used to amplify an optical signal directly, comprises optical amplifier exhibiting net phase-mismatch selected to at least partially reduce gain-induced phase-matching during operation |
| Abstract: An optical amplifier, such as an optical waveguide amplifier (e.g., an optical fiber amplifier or a planar waveguide) or a non-guiding optical amplifier, that exhibits a net phase-mismatch selected to at least partially reduce gain-induced phase-matching during operation thereof is disclosed. In one aspect of the invention, an optical amplifier structure includes at least one optical amplifier having a length and a gain region. The at least one optical amplifier exhibits a net phase-mismatch that varies along at least part of the length thereof selected to at least partially reduce gain-induced phase-matching during operation thereof. |
| Use: The optical amplifier structure is used to amplify an optical signal directly, without the need to first convert it to an electrical signal. |
| Advantage: The optical amplifier exhibits net phase-mismatch selected to at least partially reduce gain-induced phase-matching during operation. The optical amplifier exhibits a net phase-mismatch that varies along at least part of its length selected to at least partially reduce gain-induced phase-matching during its operation. |
| Novelty: An optical amplifier structure comprises at least one optical amplifier including a length and a gain region. The optical amplifier exhibits a net phase-mismatch that varies along at least part of its length selected to at least partially reduce gain-induced phase-matching during its operation. The net phase-mismatch is controlled by longitudinally varying at least one of material dispersion, modal dispersion, or nonlinear phase-mismatch of the optical amplifier. |
