Failure of the α-factor in describing QD laser dynamical instabilities and chaos
Benjamin Lingnau, Kathy Lüdge, Weng W. Chow +1
We show that the long-established concept of a linewidth-enhancement factor αto describe carrier-induced refractive index changes in semiconductor lasers breaks down in quantum dot…

Layer number determination in graphene using out-of-plane vibrations
Felix Herziger, Patrick May, Janina Maultzsch
We present a double-resonant Raman mode in few-layer graphene, which is able to probe the number of graphene layers reliably. This so-called N mode on the low-frequency side of the…
