Achieving on-chip optical signal isolation is a fundamental difficulty in integrated photonics 1 . The need to overcome this difficulty is becoming increasingly urgent, especially with the emergence of silicon nano-photonics 2 , 3 , 4 , which promises to create on-chip optical systems at an unpreced...
