A stable laser source is an essential requirement for many photonics-related applications in data communications, telecommunications, quantum information, microwave photonics, and biomedical sensing and diagnostics systems. In such systems, laser provides the requisite light source to various devices, but reflections from such devices back into the laser causes laser instability, fluctuations, noise and even failures. Hence, most practical implementations require the use of optical isolators at the output of the laser to allow light transmission in only the forward direction. However, a true optical isolator cannot be realized without the use of magneto-optical materials, which are extremely costly to integrate into low-cost, high-volume silicon photonic platforms. Often, the associated packaging cost increases the price of a laser by ten-fold. A new topology for optical isolation, compatible to silicon photonic and CMOS platforms, is critically needed to ensure better performance and feasibility for current and future optical products. This collaborative project between UBC, Intel and Lumerical will focus on analyzing and developing such a new topology, with potential impact to the large field of silicon photonics applications.

稳定的激光源是数据通信、电信、量子信息、微波光子学以及生物医学传感和诊断系统中许多光子学相关应用的基本要求。在此类系统中，激光为各种设备提供必需的光源，但从此类设备反射回激光器会导致激光不稳定、波动、噪声甚至故障。因此，大多数实际的实现需要在激光器的输出端使用光学隔离器，以允许光仅在前向传输。然而，如果不使用磁光材料，就无法实现真正​​的光隔离器，而将磁光材料集成到低成本、大批量的硅光子平台中的成本极高。通常，相关的包装成本会使激光器的价格增加十倍。为了确保当前和未来光学产品更好的性能和可行性，迫切需要一种与硅光子和 CMOS 平台兼容的新型光学隔离拓扑。 UBC、英特尔和 Lumerical 之间的这个合作项目将重点分析和开发这种新的拓扑，对硅光子应用的大领域具有潜在影响。
