摘要：

Transition from superconductive to resistive state caused by infrared radiation and bias current pulses was investigated in order to minimize switching time tau and driving power W. Experimental results for Nb microstrips confirm the correctness of calculations based on the model of electron heating. For Nb switches, tau 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 x 2 x 0, 15-mu-m2, W was 10 nW and it can be further reduced to the order of several mu-W by decreasing the volume of the sample.
