We report on the design aspects of high performance diode lasers for application in high-brightness spectral beam combining and coherent beam combining modules. Key performance trade-offs are identified and potential solutions are explored.

Design and simulation of high-speed nanophotonic electro-optic modulators (2014)
Conference Proceeding
Kaunga-Nyirenda, S. N., Dias, H. K., Lim, J. J., Bull, S., Malaguti, S., Bellanca, G., & Larkins, E. C. (2014). Design and simulation of high-speed nanophotonic electro-optic modulators. In Numerical Simulation of Optoelectronic Devices, 2014. https://doi.org/10.1109/nusod.2014.6935329

In this work, an ultracompact electro-optic modulator based on refractive index modulation by plasma dispersion effect in PhC all-optical gate (AOG) is proposed. The index modulation is achieved by applying a time-varying bias voltage across the elec... Read More about Design and simulation of high-speed nanophotonic electro-optic modulators.
