Mode Stabilization Mechanism of Buried-Waveguide Lasers with Lateral Diffused Junctions
ثبت نشده
چکیده
The mode stabilization behavior of the buried active wave guide with lateral diffused junction is theoretically investigated. The study shows that for an active waveguide of width around 5 pm with a lateral diffused junction in the middle, the single fundamental transverse mode is preferred as the injection level is raised. The theoretical results are found to be in good agreement with experimental results observed in the groove transverse junction InCaAsP/InP laser.

AIGaAs inverted strip buried heterostructure lasers
Inverted strip buried heterostructure lasers have been fabricated. These lasers have threshold currents and quantum efficiencies that are comparable to those of conventional buried heterostructure lasers. The optical mode is confined by a weakly guiding strip loaded waveguide which makes possible operation in the fundamental transverse mode for larger stripe widths than is possible for conventi...
متن کاملLateral Modes in Quantum Cascade Lasers
Abstract: We will examine the waveguide mode losses in ridge-guided quantum cascade lasers. Our analysis illustrates how the low-loss mode for broad-ridge quantum cascade lasers (QCLs) can be a higher-order lateral waveguide mode that maximizes the feedback from the sloped ridge-wall regions. The results are in excellent agreement with the nearand far-field data taken on broad-ridge-guided quan...
متن کاملDemonstration of air-guided quantum cascade lasers without top claddings.
We report on quantum cascade lasers employing waveguides based on a predominant air confinement mechanism in which the active region is located immediately at the device top surface. The lasers employ ridge-waveguide resonators with narrow lateral electrical contacts only, with a large, central top region not covered by metallization layers. Devices based on this principle have been reported in...

متن کاملReduced loss and improved mode discrimination in resonant optical waveguide arrays
Coherent laser arrays designed using resonant optical waveguides (ROWs) have proven to offer one of the most promising methods of monolithic beam combining in diode lasers. However, the high lateral transmission that provides strong optical coupling also leads to increased loss – a detriment to laser efficiency and performance. Presented is a derivation of additional design rules to eliminate l...
