| 摘要 |
Arrayed waveguide grating (AWG) circuits are disclosed, having different radii in the slab regions to supplement and/or replace other mechanical techniques which enable athermal AWGs. Dual band, interleaved pairs of athermal AWGs are also disclosed, with improved cost space and center wavelength properties, for, e.g., optical line terminal (OLT), and remote node (RN) applications. |
