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...

Modeling curved carbon fiber composite (CFC) structures in the transmission-line modeling (TLM) method (2015)
Journal Article

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...

A versatile all-optical parity-time signal processing device using a Bragg grating induced using positive and negative Kerr-nonlinearity (2015)
Journal Article

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...

Impact of dispersive and saturable gain/loss on bistability of nonlinear parity–time Bragg gratings (2014)
Journal Article

We report on the impact of realistic gain and loss models on the bistable operation of nonlinear parity–time (PT) Bragg gratings. In our model we include both dispersive and saturable gain and show that levels of gain/loss saturation can have a signi...

Ultrafast optical switching using parity-time symmetric Bragg gratings (2013)
Journal Article

This paper reports on time-domain modeling of an optical switch based on the parity–time (PT) symmetric Bragg grating. The switching response is triggered by suddenly switching on the gain in the Bragg grating to create a PT-symmetric Bragg grating....
