Mode Competition in Gas and Semiconductor Lasers
Philip F. Bagwell
The output spectrum of both gas and semiconductor lasers usually contains more than one frequency. Multimode operation in gas versus semiconductor lasers arises from different phys…
Excess Currents Larger than the Point Contact Limit in Normal Metal -Superconducting Junctions
Richard Riedel, Philip F. Bagwell
In a point contact NS junction, perfect Andreev reflection occurs over a range of voltages equal to the superconducting energy gap, producing an excess current of $I_{exc} = (4/3)(…
Supercurrent switching in Three- and Four- Terminal Josephson Junctions
H. Tolga Ilhan, Philip F. Bagwell
Control of the Josephson current by varying a gate current has recently been demonstrated in both 4-terminal and 3-terminal junctions. We show that, when the the gates are weakly c…
Andreev Level Spectroscopy and Josephson Current Switching in a 3-Terminal Josephson Junction
H. Tolga Ilhan, H. Volkan Demir, Philip F. Bagwell
We calculate the electrical currents through a superconductor - insulator - superconductor junction which is also weakly coupled to a normal metal side probe. The voltage appli…
