Passive Optical Diode on Semiconductor Substrate

摘要

An optical device includes a first optical cavity, a second optical cavity, a first light guide and a second light guide. Each of the first and second optical cavities is formed on a semiconductor substrate, and is configured to store light. The first light guide has an input, and is optically coupled to the first optical cavity by a first coupling strength. In addition, the first light guide is optically coupled to the second optical cavity by a second coupling strength. The second light guide has an output, and is coupled to the second optical cavity by a third coupling strength. The first coupling strength is greater than the second coupling strength, and the third coupling strength is greater than the second coupling strength.
