FIG. 1.

SEM micrograph of the porous InP (111) membrane. The inset shows a top view of the pores.

FIG. 2.

Experimental setup for investigating THz emission from InP. The InP samples are oriented at an angle of incidence of 45°. BS is a beam splitter, HWP is a half-wave plate, P is a polarizer, M are mirrors, ODL is an optical delay line, L1 and L2 are lenses, PM are parabolic mirrors, QWP is a quarter-wave plate, WP is a Wollaston prism, PD are photodiodes, and LIA is a lock-in amplifier.

FIG. 3.

Measured THz wave forms in the time domain from bulk (a) and porous (b) InP samples. Insets show the frequency spectrum, taken as the Fourier transform of the time domain signals.
