Fast relaxation of hot carriers by impact ionization in semiconductor nanocrystals : role of defects

Guy Allan, Christophe Delerue

We present calculations predicting that defects at the surface of semiconductor nanocrystals have a strong influence on the dynamics of hot carriers after photoexcitation. The relaxation of excited carriers by impact ionization of carriers trapped on deep levels is efficient, in particular in the…

2x2 InP optical switching matrix based on carrier-induced effects for 1.55-µm applications

Malek Zegaoui, Nargess Choueib, Joseph Harari, Didier Decoster, V. Magnin, X. Wallart, Jean Chazelas

This letter demonstrates a 2 × 2 low optical crosstalk and low power consumption switching matrix device based on carrier-induced effects on an InP substrate. The matrix device comprises two digital optical switches (DOSs) with a wide multimode Y-junction associated with a sinusoidal passive…
