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.

稳定的激光源是许多与光子相关的应用程序中的重要要求，这些应用在数据通信，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。在这样的系统中，激光为各种设备提供了必要的光源，但是从这些设备回到激光器中的反射会导致激光不稳定性，波动，噪声甚至故障。因此，大多数实际实现都需要在激光器的输出处使用光学隔离器，以仅允许向前方向发射光。但是，如果没有使用磁光材料，将无法实现真正​​的光学隔离器，该材料将集成到低成本，高体积的硅光子平台中是非常昂贵的。通常，相关的包装成本将激光器的价格提高了十倍。非常需要与硅光子和CMOS平台兼容的光学隔离拓扑，以确保对当前和将来的光学产品的更好性能和可行性。 UBC，Intel和Lumerical之间的合作项目将重点放在分析和开发这种新的拓扑结构上，并可能影响硅光子学应用程序的大型领域。
