We report our observation of the signature of photon periodic orbits in the spontaneous emission spectra of large-aperture vertical-cavity surface-emitting lasers (VCSELs). The high-resolution measurement clearly demonstrates that over a thousand cavity modes with a narrow linewidth can be perfectly exhibited in the spontaneous emission spectrum just below the lasing threshold. The Fourier-transformed spectrum is analyzed to confirm that the spontaneous emission spectra of large-aperture VCSELs can be exploited to analogously investigate the energy spectra of the 2D quantum billiards.
我们报告了在大孔径垂直腔面发射激光器(VCSEL)的自发发射光谱中光子周期轨道特征的观测结果。高分辨率测量清楚地表明,在激光阈值以下的自发发射光谱中,可以完美地显示出一千多个具有窄线宽的腔模。对傅里叶变换后的光谱进行了分析,以确认大孔径 VCSEL 的自发发射光谱可用于类似地研究二维量子台球的能谱。
