Supermode analysis and characterization of the coherent vertical cavity surface emitting laser array
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-08-01

Coherently coupling multiple elements in vertical-cavity surface-emitting laser arrays
… individual addressability provides a means for supermode engineering. A simulation model for linear leaky-mode VCSEL arrays is developed in order to predict the lasing coherent supermode for a specified array structure and relative biasing. The simulation model is verified through comparison to …

Development of ultrashort pulse fiber lasers for optical communication utilizing semiconductor devices
… harmonically mode-locked fiber laser, improving supermode suppression by eliminating pulse dropouts.

Tailoring the emission of stripe-array diode lasers with external cavities to enable nonlinear frequency conversion
… of such an array is characterized by a so called supermode. However, for the free running stripe-array mode competition between several supermodes occurs because of the lack of wavelength stabilization. This leads to power fluctuations, spectral instabilities and poor beam quality. Thus, it was …

Measurements of FEL dynamics
… the superradiant scaling laws predicted by the supermode theory. An important consequence of this observation is that it indicates that shorter and more intense optical pulses may be produced by increasing the bunch charge and reducing optical cavity losses.

Optical Fibers for Space-Division Multiplexed Transmission and Networking
… modal crosstalk in conjunction with DMGD, supermodes in CMCFs have been proposed. The properties of supermodes were investigated using the coupled-mode theory. The immediate benefits include high mode density and large effective area. In supermode structures, core-to-core coupling is …

The taiji and infinity-loop microresonators: examples of non-hermitian photonic systems
… allowing selective excitation of a single supermode. By adjusting the relative phase and amplitude between the excitation fields, the splitting in the transmission spectrum can be eliminated, resulting in improved quality factors and eigenvalue measurements. It is shown that this …
