通过结构设计与电流调控，显著降低垂直腔面发射激光器极化锁定所需功率。
Enhanced Polarization Locking in VCSELs
- 定制氧化物孔径结合电流调谐，增强极化锁定能力。
- 注入功率低至3.6 μW，锁定范围明显扩大。
- 适用于极化编码的新型计算系统，如伊辛计算机。
尽管垂直腔面发射激光器（VCSELs）的光注入锁定（OIL）已被广泛研究，但其极化动力学仍关注较少。近期研究表明，通过OIL实现极化锁定或可支持新型计算应用，如极化编码的伊辛计算机。然而，VCSEL固有的极化偏好和有限的极化切换能力限制了其应用。为此，我们制备了具有定制氧化物孔径设计的VCSEL，并结合偏置电流调节，研究其对极化锁定的综合影响。实验表明，该方法将所需注入功率降至最低3.6 μW，同时扩展了锁定范围。通过自旋翻转模型（SFM）分析幅度各向异性和偏置电流对极化锁定的影响，结果与实验高度一致。
原文摘要 · Abstract (English)
While optical injection locking (OIL) of vertical-cavity surface-emitting lasers (VCSELs) has been widely studied in the past, the polarization dynamics of OIL have received far less attention. Recent studies suggest that polarization locking via OIL could enable novel computational applications such as polarization-encoded Ising computers. However, the inherent polarization preference and limited polarization switchability of VCSELs hinder their use for such purposes. To address these challenges, we fabricate VCSELs with tailored oxide aperture designs and combine these with bias current tuning to study the overall impact on polarization locking. Experimental results demonstrate that this approach reduces the required injection power (to as low as 3.6 μW) and expands the locking range. To investigate the impact of the approach, the spin-flip model (SFM) is used to analyze the effects of amplitude anisotropy and bias current on polarization locking, demonstrating strong coherence with experimental results.
