Minimum reflection channel in amplifying random media
Seng Fatt Liew, Hui Cao
We present a numerical study on the minimum reflection channel in a disordered waveguide and its modification by coherent amplification of light. The minimum reflection channel is…
Control of mesoscopic transport by modifying transmission channels in opaque media
Raktim Sarma, Alexey Yamilov, Seng Fatt Liew +2
While controlling particle diffusion in a confined geometry is a popular approach taken by both natural and artificial systems, it has not been widely adopted for controlling light…
Coherent control of photocurrent in a strongly scattering photoelectrochemical system
Seng Fatt Liew, Sebastien M. Popoff, Stafford W. Sheehan +4
A fundamental issue that limits the efficiency of many photoelectrochemical systems is that the photon absorption length is typically much longer than the electron diffusion length…
Modification of light transmission channels by inhomogeneous absorption in random media
Seng Fatt Liew, Hui Cao
Optical absorption is omnipresent and very often distributed non-uniformly in space. We present a numerical study on the effects of inhomogeneous absorption on transmission eigench…
