We have designed a new, optimal, inverse taper structure to guide light on chip from an external laser. This taper helps convert the optical mode from a tightly confined, Si-microphotonic waveguide to a standard, large-mode-diameter, optical fiber. Without such a device, ~95% of the light is lost and with such a device only ~10% is lost. Teraxion, our industrial collaborator, has a strong need for such a device. They are moving away from coupling light to their devices using vertical gratings and moving towards butt-coupled tapers, such as the device that we are proposing to make here. Butt-coupled tapers offer the advantages of higher bandwidth and reduced alignment constraints. Here we propose to build the first experimental demonstration of our modeled, optimal. inverse taper structures.

我们设计了一种新的，最佳的，倒锥形结构，引导光从外部激光器在芯片上。这 锥形有助于将光模从紧密限制的Si微光子波导转换为标准， 大模径光纤。如果没有这样的设备，约95%的光会损失，而使用这样的设备， 只有约10%丢失。我们的工业合作伙伴Teraxion对这种设备有着强烈的需求。他们正在采取行动 远离使用垂直光栅将光耦合到他们的设备，并朝着对接耦合的锥形移动， 作为我们在这里提出的设备。对接耦合锥形具有带宽更高的优点 以及减少的对准约束。在这里，我们建议建立我们的第一个实验示范， 模型化，最佳化。倒锥形结构。
