Threshold manipulation in parity-time symmetric microresonator chain (2015)
Presentation / Conference Contribution
Phang, S., Vukovic, A., Creagh, S., Benson, T. M., Gradoni, G., & Sewell, P. D. Threshold manipulation in parity-time symmetric microresonator chain. Presented at 9th International Congress on Advanced Electromagnetic Materials in Microwaves and Optics

This paper analyses the eigenfrequencies of an infinitely long chain of microresonators with PT symmetry. The results show that the depth of modulation of the real part of the refractive index can be used to control the threshold point of the PT stru...

Parity-time chain of whispering-gallery mode resonators (2015)
Presentation / Conference Contribution
Phang, S., Vukovic, A., Creagh, S., Benson, T. M., Gradoni, G., & Sewell, P. D. Parity-time chain of whispering-gallery mode resonators. Presented at META15, the 6th International Conference on Metamaterials, Photonic Crystals and Plasmonics

The paper analyses the dispersion characteristics of an infinitely long PT chain made of whispering gallery resonators with gain/loss modulation. The results show that the appearance of the threshold breaking point depends not only on both of couplin... Read More about Parity-time chain of whispering-gallery mode resonators.

Parity-time symmetric coupled microresonators with a dispersive gain/loss (2015)
Journal Article

The paper reports on the coupling of Parity-Time (PT)-symmetric whispering gallery resonators with realistic material and gain/loss models. Response of the PT system is analyzed for the case of low and high material and gain dispersion, and also for...

A new embedded model for curved thin panels is developed in the transmission line modeling (TLM) method. In this model, curved panels are first linearized and then embedded between adjacent 2-D TLM nodes allowing for arbitrary positioning between adj...

The properties of gratings with Kerr nonlinearity and PT symmetry are investigated in this paper. The impact of the gain and loss saturation on the response of the grating is analysed for different input intensities and gain/loss parameters. Potentia...
