Geometric scaling limits of phase-only control in multimode coherent systems
Harikumar K Chandrasekharan
Control of coherent waves is often restricted to phase-only actuation in multimode systems, yet the resulting physical limits remain poorly understood. Here, we show that restricti…
Polarization-independent deterministic mode localization in a photonic lantern
Harikumar K Chandrasekharan, Ross Donaldson
Coherent interference in multimode photonic systems underpins scalable, high-fidelity control for beam shaping, power delivery, and signal processing, yet most existing approaches…
Resolving polarization-dependent mode dynamics in multimode fibers with 2D single-photon detector arrays
Harikumar K. Chandrasekharan, Ross Donaldson
Monitoring polarization dynamics in multimode fibers is critical for a range of applications, spanning from optical communication to sensing. Although the modal behavior of multimo…
In-situ multicore fibre-based pH mapping through obstacles in integrated microfluidic devices
Harikumar K. Chandrasekharan, Krystian L. Wlodarczyk, William N. MacPherson +1
Microfluidic systems with integrated sensors are ideal platforms to study and emulate processes such as complex multiphase flow and reactive transport in porous media, numerical mo…
