Optical Analogues for Massless Dirac Particles and Conical
... For our experiments, we fabricated a waveguide array by employing the femtosecond direct-writing approach [24] as shown in Fig. 3(a). The parameters of the writing procedure can be found in [24]. The sample consists of 40 sinusoidally shaped waveguides with alternating distances between adjacent lat ...

Stability of Continuously Pumped Atom Lasers
... quantum mechanical model must be used to calculate the linewidth of the beam coming from a pumped atom laser. Single (or few) mode quantum theories have been used to describe continuously pumped atom lasers [11]. Unfortunately, these models cannot describe the multimode behavior of the atom laser su ...

Lobster eye: Data processing from two 1D modules
... In picture Fig. 1 is illustration of two independent 1D Lobster eye modules with two independent detectors. In case of two 1D optics, the focus length can be same, for horizontal and vertical module, but advantage in different focal length is that modules can be put side by side and then can be used ...
