From: On-chip passive three-port circuit of all-optical ordered-route transmission
Theoretical analysis of the three-port device.
(a) Layout of the proposed three-port device of optical ordered-route transmission. (b)-(d) Principle diagrams of route-asymmetric optical transmission between (b) Port 1 and Port 2, (c) Port 2 and Port 3, (d) Port 3 and Port 1, respectively. All input light own the same power at an aligned resonant wavelength of the two MRRs. Abbreviations are labelled as follows: Pin, input power; Pmaj, major power; Pmin, minor power; WL, larger width; WS, smaller width; GL, larger gap; GS, smaller gap.
