摘要

我们证明了二维(4x4) VCSEL阵列可以设计成在稳定的同相模式下工作，与理论很好地吻合。计算表明，当元件间间距对应于反波导半波的奇(偶)整数时，会发生同(非)相模式的谐振耦合。它由27.5对AlAs-GaAs n-DBR、23对AlGaAs-GaAs p-DBR和一个包含3-InGaAs量子阱、GaAs势垒层和980nm发射的AlGaAs约束层的光学腔组成。

2-D phased-locked antiguided vertical cavity surface emitting laser arrays

We demonstrate that 2D (4x4) VCSEL arrays can be designed to operate in a stable in-phase mode in good agreement with theory. Calculations show resonant couplings for the in-phase (out-of-phase) mode occurs when the inter-element spacing corresponds to an odd (even) integral number of half-waves of the antiguide. It consists of 27.5 pairs of AlAs-GaAs n-DBR, 23 pairs of AlGaAs-GaAs p-DBR and an optical cavity which includes 3-InGaAs quantum wells, GaAs barrier layers, and AlGaAs confinement layers for 980nm emission.
