Practical limitation on operation of nonlinear parity-time Bragg gratings (2014)
Conference Proceeding
Phang, S., Vukovic, A., Susanto, H., Benson, T. M., & Sewell, P. (2014). Practical limitation on operation of nonlinear parity-time Bragg gratings.

The paper analyses the operation of PT Bragg gratings when the dielectric material is considered to be both dispersive and nonlinear and gain and loss are saturable. The paper demonstrates the application of the nonlinear PT Bragg Grating as an optic... Read More about Practical limitation on operation of nonlinear parity-time Bragg gratings.

Impact of dispersive and saturable gain/loss on bistability of nonlinear parity–time Bragg gratings (2014)
Journal Article
Phang, S., Vukovic, A., Susanto, H., Benson, T. M., & Sewell, P. (2014). Impact of dispersive and saturable gain/loss on bistability of nonlinear parity–time Bragg gratings. Optics Letters, 39(9), 2603-2606. https://doi.org/10.1364/ol.39.002603

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...

© 2014 IEEE. The positioning of electromagnetic (EM) sources on the complex plane, though a mathematical construct, is often applied in solving EM problems with directive confined (collimated) propagation characteristics. Equivalent dipole modeling,... Read More about Complex locations of equivalent dipoles for improved characterization of radiated emissions.

A novel photonic crystal band-pass filter using degenerate modes of a point-defect microcavity for terahertz communication systems (2014)
Journal Article

Compact devices are important for the realization of terahertz communications systems. This article proposes a novel photonic crystal-based device for realizing microminiature, high-selectivity high Q band-pass filters (BPF) and the design of a dual-...

Saturable and dispersive parity-time symmetric directional coupler: a transmission-line modelling study (2014)
Conference Proceeding
Phang, S., Vukovic, A., Benson, T. M., Creagh, S., Sewell, P., & Gradoni, G. (2014). Saturable and dispersive parity-time symmetric directional coupler: a transmission-line modelling study.

In this paper, numerical modelling of Parity-Time (PT) coupled waveguides is reported. The PT coupled waveguide structure consists of two coupled slab waveguides based on GaAs material with gain/loss material parameter models, including both dispersi...

Modelling of dispersive PT-symmetric Bragg grating (2014)
Conference Proceeding
Phang, S., Vukovic, A., Susanto, H., Benson, T. M., & Sewell, P. (2014). Modelling of dispersive PT-symmetric Bragg grating.

This paper reports on the time-domain numerical model of a parity-time Bragg grating with saturated and dispersive gain. The model is compared against the ideal PT scenario where the gain is constant and unsaturated for all frequencies.
