1.3 m broadband swept sources with enhanced nonlinear effects
In this work, a new structure is used to enhance the nonlinear effect in the cavity, which improves the performance of the 1.3[Formula: see text][Formula: see text]m broadband swept source.The swept source adopts a semiconductor optical amplifier (SOA), a circulator, a coupler, and a tunable filter.In the structure, the light passes through the non
