Power and spectral characterization of photonic integrated circuit based axicon like lens

Rijan Maharjan, Sanket Bohora, Pravin Bhattarai +5

We demonstrate an on-chip Silicon-on-Insulator (SOI) axicon etched using a low resolution (200 nm feature size, 250 nm gap) deep-ultraviolet lithographic fabrication. The axicon co…

Tight focal spots using azimuthally polarised light from a Fresnel cone

R. D. Hawley, R. Offer, N. Radwell +1

When focusing a light beam at high numerical aperture, the resulting electric field profile in the focal plane depends on the transverse polarisation profile, as interference betwe…

Stationary States and Instabilities of a Mobius Fibre Resonator

Calum Maitland, Matteo Conforti, Arnaud Mussot +1

We examine the steady state and dynamic behaviour of an optical resonator comprised of two interlinked fibre loops sharing a common pump. A coupled Ikeda map models with great accu…

Diabolical Points in Coupled Active Cavities with Quantum Emitters

Jingnan Yang, Chenjiang Qian, Xin Xie +17

In single microdisks, embedded active emitters intrinsically affect the cavity mode of microdisks, which results in a trivial symmetric backscattering and a low controllability. He…
