| Popis: |
We present a coherent coupling scheme for mid‐infrared quantum cascade lasers. Based on far field analysis, fundamental lateral modes are realized in Y‐coupled resonators, which are locked in phase. The concept enhances the output power of a single facet coherent emitter, while maintaining good beam quality due to modal control. High flexibility in the choice of material system, emission wavelength and waveguide design combined with mature processing techniques make quantum cascade lasers an ideal candidate to gain insight into coherent spacial beam combining for high power laser applications. |
