Lattice-matched GaInAs p-i-n diodes of different i-region thicknesses have been MBE grown on n-type InP (100) and (111) crystallographic orientation substrates. It has been found that terahertz emission from such structures when illuminated with femtosecond laser pulses can be more efficient than that from the known to date best surface terahertz emitter (111) p-InAs. The explanation of the terahertz generation mechanism from p-i-n diodes is based on ultrafast photocurrent effects. Anisotropic transient photocurrents causing the 3ϕ azimuthal angle dependence are observed in the sample on (111) substrate. These p-i-n structures allow covering a technologically important 1.55 μm range and may provide controllability and compactness of a THzTDS system when biased with an external voltage source.

Faddeev Model

Through an ansatz specifying the azimuthal-angle dependence of the solution, the static field equation for vortex of the Faddeev model is converted to an algebraic ordinary differential equation. An approximate analytic expression of the vortex solution is explored so that the energy per unit vortex length becomes as small as possible. It is observed that the minimum energy of vortex is approximately proportional to the integer which specifies the solution.
