Mesa Orientation Engineering for Polarization Locking in VCSELs
Zifeng Yuan, Wenkai Shan, Tingting Chen +2
While polarization stability is common in many optical systems, intentional polarization bi-stability is also important for polarization-encoded computing. We propose a mesa orient…

Engineering Polarization Switching in VCSELs with Custom Aperture Shapes
Zifeng Yuan, Dewen Zhang, Hong-Lin Lin +1
We experimentally fabricate and measure vertical-cavity surface-emitting lasers (VCSELs) with custom aperture shapes, demonstrating predictable polarization control and switching,…

Perfect Quantum State Revivals: Designing Arbitrary Potentials with Specified Energy Levels
Aaron Danner, Tomáš Tyc
It is known that there exist a limited number of analytic potentials with the unusual property that any bound quantum state therein will be periodic in time. This is known as a per…
