提出了一种垂直腔面发射激光器（VCSEL）横模选择的方法。引入环形反相SiO2层，滤除与附加层强度分布重叠的模式。采用考虑氧化层孔径大小的有效折射率法确定了环形腔的内、外径。制作了常规参考器件和两轮环形SiO2 VCSEL的验证性研究，并进行了表征。与常规VCSEL相比，具有环形SiO2层的VCSEL在整个电流范围内发射两个稳定的横模。该方法为解决未来少模光通信对器件的要求提供了一种新的思路。
We demonstrated a method of transverse mode selection of vertical-cavity surface-emitting lasers (VCSELs). A ring-shaped anti-phase SiO2layer was introduced to filter the modes whose intensity distribution overlapped with the extra layer. The effective index method considering the size of the oxide aperture was applied to decide the inner/outer radius of the ring. Conventional reference device and two-round of confirmatory studies of ring-shaped SiO2VCSEL were fabricated and characterized. In comparison with the spectra of the conventional VCSEL, the VCSELs with ring-shaped SiO2layer emitted two stable transverse modes over the entire current range. This method may offer a new idea to solve the device request for the few-mode optical communications in the future.
