Journal Article
Pezeshki, H., Wright, A. J., & Larkins, E. C. (2022). Ultra-compact and ultra-broadband hybrid plasmonic-photonic vertical coupler with high coupling efficiency, directivity, and polarisation extinction ratio. IET Optoelectronics, 16(3), 124-132. https://doi.org/10.1049/ote2.12063

An ultra-compact, ultra-broadband vertical coupler for dense photonic integrated circuits is reported with a 1.07×0.62μm2 wavelength-scale footprint. This hybrid plasmonic-photonic coupler uses a unique two-plane plasmonic nanoantenna array on a sili...

Factors influencing brightness and beam quality of conventional and distributed Bragg reflector tapered laser diodes in absence of self-heating (2014)
Journal Article
Kaunga-Nyirenda, S. N., Bull, S., Lim, J. J., Hasler, K., Fricke, J., & Larkins, E. C. (2014). Factors influencing brightness and beam quality of conventional and distributed Bragg reflector tapered laser diodes in absence of self-heating. IET Optoelectronics, 8(2), https://doi.org/10.1049/iet-opt.2013.0082

In this study, the authors examine some of the factors affecting the brightness and the beam quality of high-power tapered lasers. The large volume resonators required to achieve a high-power, high-brightness operation make the beam quality sensitive...
