Abstract
Optical circuits are disclosed having one or more alignment guides for aligning the circuits with optical fiber arrays. The alignment guides have loop type optical paths extending between first and second ends, which are positioned in a fixed location relative to waveguides in the optical circuit allowing alignment of an optical fiber array with the circuit using a light source and a light detector connected to the array. In addition, methods and systems are disclosed for aligning optical fiber arrays with waveguides in an optical circuit.
