Mode locking via delayed orthogonal-polarization reinjection in semiconductor VCSELs
T. Wang, Y. Ma, Z. Li +7
We demonstrate harmonic mode-locking in a semiconductor VCSEL using polarization-controlled delayed feedback. By integrating a rotatable /2-plate within an external cavity, we a…

Fast square-oscillations in semiconductor VCSELs with delayed orthogonal polarization feedback
Tao Wang, Zhicong Tu, Yixing Ma +5
We present an experimental investigation into the generation of self-sustained and fast square oscillations from the TE mode of semiconductor VCSELs with delayed orthogonal polariz…
