DOI: 10.1109/jphot.2016.2640560
Abstract: We investigate experimentally the state bistability driven by current or feedback in a 1550 nm vertical-cavity surface-emitting laser (1550 nm-VCSEL) with negative optoelectronic feedback (NOEF). The results show that through continuously varying the controlled parameters such as… read more here.
