Quantum Decay of an Optical Soliton
Stuart Ward, Rouzbeh Allahverdi, Arash Mafi
Optical solitons are known to be classically stable objects which are robust to perturbations. In this work, we show that due to quantum mechanical effects, an optical soliton that…
Analytical formulation of a high-power Yb-doped radiation balanced fiber laser
Mostafa Peysokhan, Brian Topper, Esmaeil Mobini +1
We present an analytical solution for a radiation balanced fiber laser, in which no net heat is generated during lasing operation due to cooling by anti-Stokes fluorescence. The re…
Laser Cooling of a Yb Doped Silica Fiber by 18 Kelvin From Room Temperature
Brian Topper, Mostafa Peysokhan, Alexander R. Albrecht +10
A ytterbium doped silica optical fiber has been cooled by 18.4K below ambient temperature by pumping with 20W of 1035nm light in vacuum. In air, cooling by 3.6K below ambient was o…
Optical Characterization of Disordered Yb-doped Silica Glass Anderson Localizing Optical Fiber
Cody Bassett, Matthew Tuggle, Johan Ballato +1
We investigate and report the optical and laser characteristics of a ytterbium-doped transverse Anderson localizing optical fiber to develop a fundamental understanding of the ligh…
A Supersymmetric Approach to the Problem of Micro-bending Attenuation in Optical Waveguides
Stuart Ward, Rouzbeh Allahverdi, Arash Mafi
Micro-bending is a well-known source of loss in optical waveguides. By treating the micro-bending as a stochastic process, the problem of loss mitigation can be modeled in terms of…
Laser-induced anti-Stokes fluorescence cooling of ytterbium-doped silica glass by more than 6 Kelvin
Mostafa Peysokhan, Saeid Rostami, Esmaeil Mobini +12
Laser cooling of a solid is achieved when a coherent laser illuminates the material, and the heat is extracted by resulting anti-Stokes fluorescence. Over the past year, net solid-…
