Figure 4: Time-domain measurements.
From: Gate-controlled generation of optical pulse trains using individual carbon nanotubes
A (13,3) nanotube is measured with Va=+1.2 V, Vb=−1.8 V and f=5,011 Hz. The spectral integration window for IPL is from λem=1,440 to 1,490 nm. (a,b) Time dependence of gate voltage and integrated PL, respectively. (c) Integrated PL as a function of time and τ. (d) Temporal evolution of integrated PL for τ=50, 100 and 150 μs. For b–d, P=50 μW is used. (e) Integrated PL as a function of time and P. (f) Laser power dependence of pulse width.
