Spectral control of broadband light through random media by wavefront shaping
Spectral control of broadband light random media wavefront shaping Optics
2012/5/31
A random medium can serve as a controllable arbitrary spectral filter with spectral resolution determined by the inverse of the interaction time of the light in the medium. We use wavefront shaping to...
Experimental demonstration of a broadband array of invisibility cloaks in the visible frequency range
Experimental demonstration broadband array invisibility cloaks visible frequency range Optics
2012/4/20
Very recently Farhat et al. [1] have suggested that arrays of invisibility cloaks may find important applications in low-interference communication, noninvasive probing, sensing and communication netw...
Controllable ultra-broadband slow light in a warm Rubidium vapor
Controllable ultra-broadband slow light Rubidium vapor Optics
2011/8/18
Abstract: We study ultra-broadband slow light in a warm Rubidium vapor cell. By working between the D1 and D2 transitions, we find a several-nm window centered at 788.4 nm in which the group index is ...
Prospects of coherent control in turbid media: Bounds on focusing broadband laser pulses
Prospects coherent control turbid media broadband laser pulses
2011/8/11
Abstract: We study the prospects of controlling transmission of broadband and bi-chromatic laser pulses through turbid samples. The ability to focus transmitted broadband light is limited via both the...

Interstitial BiO molecule broadband IR luminescence bismuth-doped silica glass
2011/8/18
Abstract: IR luminescence and absorption in bismuth-doped silica glass-core fibers observed recently (see [arXiv:1106.2969v1 [physics.optics]) are argued to be caused by transitions in interstitial Bi...
Polypropylene Embedded Metal-Mesh Broadband Achromatic Half Wave Plate for Millimeter Wavelengths
Polypropylene Embedded Metal-Mesh Broadband Achromatic Half Wave Plate Millimeter Wavelengths
2011/8/17
Abstract: We describe a novel multi-layered metal mesh achromatic half wave plate for use in astronomical polarimetric instruments. The half wave plate is designed to operate across the frequency rang...

2011/8/4
Abstract: We suggest a broadband optical unidirectional arrayed nanoantenna consisting of equally spaced nanorods of gradually varying length. Each nanorod can be driven by near-field quantum emitters...
Adaptation of a commercial Raman spectrometer for multiline and broadband laser operation
