Intracavity frequency-doubled degenerate laser
Seng Fatt Liew, Sebastian Knitter, Sascha Weiler +5
We develop a green light source with low spatial coherence via intracavity frequency doubling of a solid-state degenerate laser. The second harmonic emission supports many more tra…
Controlling mode competition by tailoring the spatial pump distribution in a laser: A resonance-based approach
Alexander Cerjan, Brandon Redding, Li Ge +3
We introduce a simplified version of the steady-state ab initio laser theory for calculating the effects of mode competition in continuous wave lasers using the passive cavity reso…
Correlation-enhanced control of wave focusing in disordered media
Chia Wei Hsu, Seng Fatt Liew, Arthur Goetschy +2
A fundamental challenge in physics is controlling the propagation of waves in disordered media despite strong scattering from inhomogeneities. Spatial light modulators enable one t…
Evanescently coupled multimode spiral spectrometer
Brandon Redding, Seng Fatt Liew, Yaron Bromberg +2
We designed a high-resolution compact spectrometer based on an evanescently-coupled multimode spiral waveguide. Interference between the modes in the waveguide forms a wavelength-d…
Broadband multimode fiber spectrometer
Seng Fatt Liew, Brandon Redding, Michael A. Choma +2
A general-purpose all-fiber spectrometer is demonstrated to overcome the trade-off between spectral resolution and bandwidth. By integrating a wavelength division multiplexer with…
