Ultra-compact and ultra-broadband hybrid plasmonic-photonic vertical coupler with high coupling efficiency, directivity, and polarisation extinction ratio (2022)
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...

Hybrid photonic-plasmonic platform for high-throughput single-molecule studies (2019)
Journal Article
Mossayebi, M., Parini, A., Wright, A. J., Somekh, M. G., Bellanca, G., & Larkins, E. C. (2019). Hybrid photonic-plasmonic platform for high-throughput single-molecule studies. Optical Materials Express, 9(6), 2511-2522. https://doi.org/10.1364/OME.9.002511

We present the design and numerical characterization of a hybrid photonic-plasmonic nanoresonator comprised of a 2D photonic crystal (PhC) cavity, a gold bowtie nanoantenna (BNA) and a silicon dioxide, SiO2, spacer. This device is designed to serve a... Read More about Hybrid photonic-plasmonic platform for high-throughput single-molecule studies.

Investigating the use of a hybrid plasmonic-photonic nanoresonator for optical trapping using finite-difference time-domain method (2016)
Journal Article
Mossayebi, M., Wright, A., Parini, A., Somekh, M., Bellanca, G., & Larkins, E. (2016). Investigating the use of a hybrid plasmonic-photonic nanoresonator for optical trapping using finite-difference time-domain method. Optical and Quantum Electronics, 48(5), doi:10.1007/s11082-016-0539-5

We investigate the use of a hybrid nanoresonator comprising a photonic crystal (PhC) cavity coupled to a plasmonic bowtie nanoantenna (BNA) for the optical trapping of nanoparticles in water. Using finite-difference time-domain simulations, we show t...

High-power operation of coherently coupled tapered laser diodes in an external cavity (2016)
Journal Article
Schimmel, G., Doyen, I., Janicot, S., Hanna, M., Georges, P., Lucas-Leclin, G., …Traub, M. (2016). High-power operation of coherently coupled tapered laser diodes in an external cavity. Proceedings of SPIE, 9733, Article 97330I. https://doi.org/10.1117/12.2211613

We demonstrate a rear-side phase-locking architecture with two high-brightness diode lasers. This technique is based on the passive phase-locking of emitters in an external cavity on their rear facet, and their coherent combination on the front facet...

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...
