Abstract

A semiconductor photonics device includes a multiple-layer coupler structure. The multiple-layer coupler structure includes a plurality of optical coupler layers, which enables the properties of the optical coupler layers to be configured to achieve efficient optical coupling for a broad spectrum of optical wavelengths. This enables the multiple-layer coupler structure to handle wide bandwidth optical signals, which enables the semiconductor photonics device to support high-bandwidth optical communication applications. Moreover, the optical coupler layers of the multiple-layer coupler device enable the performance of the multiple-layer coupler structure to be increased using less complex and less costly semiconductor manufacturing processes and techniques. Additionally, the optical coupler layers of the multiple-layer coupler structure enable the multiple-layer coupler structure to handle bidirectional transmission of optical signals, thereby enabling transmission of optical signals between various layers of the semiconductor photonics device.
