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,…

Enhanced Polarization Locking in VCSELs
Zifeng Yuan, Dewen Zhang, Lei Shi +2
While optical injection locking (OIL) of vertical-cavity surface-emitting lasers (VCSELs) has been widely studied in the past, the polarization dynamics of OIL have received far le…

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…
