多横模垂直腔面发射激光器及其波长特性∗
Multi-transverse-mo de and wavelength split characteristics of vertical cavity surface emitting laser
摘要
Abstract
We study the multi-transverse mode distributions and the wavelength splittings with different designed oxide aper-tures of the oxide-confined VCSEL. By developing the effective index model and BPM algorithm theory, the charac-teristics of transverse optical field distribution are calculated with circular aperture and ellipsoid aperture, which are compared with our experimental results of multi-wavelength spectra of high-order transverse modes. The results show that the orthogonality of the different crystal orientation modes will be broken by the oxidation-induced ellipsoid aper-ture, and the maximum wavelength spltting of the degenerated high-order mode is 0.037 nm, which can be reduced as the diameter of aperture increases. The results in this paper will provide a useful reference for multi-transverse mode locking of oxide-confined VCSELs.关键词
