Observation of rogue waves in a 980nm-laser diode subject to filtered optical feedback

International audienceIn this work, rogue waves are observed in a 980 nm laser diode subject to filtered optical feedback via an fibre Bragg grating. A rogue-wave map is established for the first time experimentally as functions of optical feedback ratio and laser current. Rogue waves in our laser system are identified as a part of low frequency fluctuation jump-ups

High-resolution low-frequency fluctuation map of a multimode laser diode subject to filtered optical feedback via a fiber Bragg grating

International audienceA highly detailed and extended map of low-frequency fluctuations is established for a high-power multi-mode 980 nm laser diode subject to filtered optical feedback from a fiber Bragg grating. The low-frequency fluctuations limits and substructures exhibit substantial differences with previous works
