Steering, Splitting and Cloning of Optical Beam in a Coherently Driven Raman Gain System
Onkar N. Verma, Tarak N. Dey
We propose an all-optical anti-waveguide mechanism for steering, splitting, and cloning of an optical beam beyond the diffraction-limit. We use a spatially inhomogeneous pump beam…

Enhancement of image resolution beyond the diffraction-limit by interacting dark resonances
Onkar N. Verma, Tarak N. Dey
We show how quantum coherence effects can be used to improve the resolution and the contrast of diffraction-limited images imprinted onto a probe field. The narrow and sharp spectr…

Optical cloning of arbitrary images beyond the diffraction limits
O. N. Verma, L. Zhang, J. Evers +1
Cloning of arbitrary images encoded onto the spatial profile of a laser beam onto that of a second beam is theoretically investigated. The two fields couple to an atomic lambda sys…
