Conf. on Lasers and Electro-Optics (CLEO 2022), San Jose, USA, May 15-20, ISBN 978-1-957171-05-0, p. SM3G.3, doi:10.1364/CLEO_SI.2022.SM3G.3 (2022).


The phase noise caused by current fluctuations in single-pass semiconductor optical amplifiers is experimentally investigated. Using low-index quantum barrier designs in prototype devices is found to reduce phase noise by 18% compared to reference designs.
