IPC: H03H11/38
Filed: 1986-01-24
Abstract: PURPOSE:To perform the function of a circulation by reversing a bias current applied to Josephson lines adjacent to both input/output terminals and selecting one line when a soliton is input from the terminal to allow the soliton to travel. CONSTITUTION:A soliton input from a Josephson line 104 is output through a Josephson line 100 from a Josephson line 105. In this case, the soliton is not input to the lines 103, 101. When the soliton is input from the line 105, the direction of the magnetic flux of the soliton is designated as 115. The positions of the lines 100, 101 with respect to the line 105 are laterally reversed at the positions of the lines 103, 110 with respect to the line 105, but since the direction of the input soliton magnetic flux is reversed between the directions 112 and 115, the soliton is output through the line 101 from a Josephson line 106. The soliton is not input to the lines 100, 101 even in this case. As described above, this circuit has a function of a circulator.
