A highly birefringent elliptical-hole terahertz (THz) fiber with a squeezed lattice is proposed. This THz fiber is formed through regular linear deformation of a circular porous fiber by squeezing it in one direction, which may be fabricated with the existing fabrication technology. By numerical ... [Appl. Opt. 48, 3943-3947 (2009)]

We present a technique to measure the frequency chirp introduced by the laser pulse amplification process in the transmitter of the Colorado State University sodium lidar system. This chirp causes a systematic radial wind bias that must be removed from the reported wind measurements. An iodine ... [Appl. Opt. 48, 3988-3993 (2009)]

In this paper we study the effect of material dispersion on the performance of a moving-optical-wedge Fourier transform spectrometer. The spectrum is thus evaluated numerically using a test spectrum source. The obtained numerical results show that the classical technique for numerical dispersion ... [Appl. Opt. 48, 3979-3987 (2009)]
