Description

Transition from superconductive to resistive state cause by infrared radiation and bias current pulses was investigated in order to minimize switching time τ and driving power W. Experimental results for Nb microstrips confirm the correctness of calculations based on the model of electron heating. For Nb switches, τ measured directly is 0,3-0,8 ns for radiation pulses and 1-3 ns for bias current pulses at T = 4.2 K, while for YBaCuO switches at T = 77 K it is expected to be several ps. For an YBaCuO sample with the dimensions of 5.2.0, 15 μm2, W was 10 mW and it can be further reduced to the order of several μW by decreasing the volume of the sample
