Spatial structure of lasing modes in wave-chaotic semiconductor microcavities
Stefan Bittner, Kyungduk Kim, Yongquan Zeng +2
We present experimental and numerical studies of broad-area semiconductor lasers with chaotic ray dynamics. The emission intensity distributions at the cavity boundaries are measur…

Electrically pumped semiconductor laser with low spatial coherence and directional emission
Kyungduk Kim, Stefan Bittner, Yongquan Zeng +3
We design and fabricate an on-chip laser source that produces a directional beam with low spatial coherence. The lasing modes are based on the axial orbit in a stable cavity and ha…
