Abstract

We demonstrate an out-of-plane optical coupling between a photonic integrated circuit (PIC) and a fiber array (FA). The presented scheme utilizes a molded glass microlens with an integrated turning mirror. We show that by expanding the beam, the alignment tolerances between the fiber and PIC assemblies are expanded by an order of magnitude. The reported coupling losses of 2.1 dB per coupler are only limited by the optical design of the off-the-shelf micro-optics.

利用转镜透镜阵列实现光子集成电路的面外光耦合

我们展示了光子集成电路（PIC）和光纤阵列（FA）之间的面外光耦合。所提出的方案利用一个模压玻璃微透镜与一个集成的旋转镜。我们表明，通过扩大光束，光纤和PIC组件之间的对准公差扩大了一个数量级。据报道，每个耦合器2.1 dB的耦合损耗仅受现成微光学光学设计的限制。
