Peyvast, N., Childs, D. T.D., Krstajic, N., Lu, Z., Matcher, S. J., Livshits, D., Shkolnik, A., Krestnikov, I. and Hogg, R. A. (2012) Self-assembled quantum dot-based swept laser source for optical coherence tomography applications.
In this work the use of two identical QD SOAs to enhance the performance of swept laser system for OCT applications is discussed, resulting in an increase in bandwidth up to 94nm. The combination of GaAs based QD SOAs and InP based QW SOAs for realizing broad bandwidth sources for OCT system is described. For the swept laser source a 154nm spectral bandwidth from 1193nm to 1347nm and an average power of 8mW is obtained and for the filtered ASE source a 225 nm bandwidth is demonstrated.
