Abstract
A device for collecting light emitted by a laser source, including an optical wave guide arranged so as to collect a light signal emitted by the laser source, by coupling. The wave guide includes a loop coupled to a laser source in two coupling zones making it possible to recover optical modes circulating along the direction opposite to the required direction for the signal output from the device.
