20100020834 | QUADRATIC NONLINEARITY-BASED HIGH-ENERGY PULSE COMPRESSOR FOR GENERATING FEW-CYCLE PULSES - A pulse compressor for compressing many-cycle femtosecond-duration high-energy pulses to near-single-cycle durations uses a single quadratic nonlinear crystal. A pulsed laser beam is controlled and its passage is aligned through the quadratic nonlinear crystal such that the detrimental effects of group-velocity mismatch are avoided, while still allowing enough nonlinear phase accumulation for compression to near-single-cycle pulse durations. To do so, the perturbation to nonlinear Schrödinger-type soliton compression due to group-velocity mismatch is minimized which requires that the soliton order must not exceed an optimal value set by the amount of group-velocity mismatch. | 2010-01-28 |

20100020836 | USE OF CURRENT CHANNELING IN MULTIPLE NODE LASER SYSTEMS AND METHODS THEREOF - Current channels, blocking areas, or strips in a semiconductor laser are used to channel injected current into the antinodal region of the optical standing wave present in the optical cavity, while restricting the current flow to the nodal regions. Previous devices injected current into both the nodal and antinodal regions of the wave, which is fed by the population inversion created in the active region by the injected electrons and holes, but inversion created in the nodal regions is lost to fluorescence or supports the creation of undesirable competing longitudinal modes, causing inefficiency. Directing current to the antinodal regions where the electric field is at its maximum causes a selected longitudinal mode to preferentially oscillate regardless of where the longitudinal mode lies with respect to the gain curve. In one embodiment, exacting fabrication of the Fabry-Perot cavity correlates the current channels to antinodal regions, vis-a vis current blocking areas, strips or segmented layers. | 2010-01-28 |

The diffusion accommodation layer comprises a material that has a higher bandgap than the bandgap of the material in the active region. Diffusion of dopants into portions of the diffusion accommodation layer forms p+/n junctions on each side of the p/n junction that exists in the active region. The material of the diffusion accommodation layer has a bandgap that is higher than the bandgap of the material of the active region, which ensures that the p+/n junctions turn on at a threshold voltage level that is higher than the threshold voltage level at which the p/n junction turns on. Because of this, the p+/n junctions are effectively turned off while the p/n junction is turned on, which causes the electrical current to be channeled away from the p+/n junctions and into the p/n junction, thereby confining the current to a particular area in the active region. | 2010-01-28 |
