正方形光学台球中的类疤痕结构和不可积性
Scar-like structures and non-integrability in a perfectly square optical billiard
摘要:
我们表明,疤痕状结构(SLS)在大口径垂直腔面发射激光器(VCSEL),甚至可以形成在一个完美的正方形的几何形状,由于光的偏振和空间自由度的相互作用。我们还表明,在系统中的耗散诱导腔模式之间的顺序,使SLS成为首选的激光阈值。更一般地,在坐标和动量空间中更局部化的模式平均具有更低的损耗。
英文摘要:
We show that scar-like structures (SLS) in a wide aperture vertical cavity surface emitting laser (VCSEL) can be formed even in a perfectly square geometry due to interaction of polarization and spatial degrees of freedom of light. We show also that dissipation in the system induces an order among the cavity modes, so that SLS become preferred at lasing threshold. More generally, modes which are more localized both in coordinate and momentum space have in average lower losses.
