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…
Principal modes in multimode fibers: exploring the crossover from weak to strong mode coupling
Wen Xiong, Philipp Ambichl, Yaron Bromberg +3
We present experimental and numerical studies on principal modes in a multimode fiber with mode coupling. By applying external stress to the fiber and gradually adjusting the stres…
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…
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…
Spatio-temporal Control of Light Transmission through a Multimode Fiber with Strong Mode Coupling
Wen Xiong, Philipp Ambichl, Yaron Bromberg +2
We experimentally generate and characterize the eigenstates of the Wigner-Smith time-delay matrix, called principal modes, in a multimode fiber with strong mode coupling. The uniqu…
