Practical limitation on operation of nonlinear parity-time Bragg gratings (2014)
Conference Proceeding

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.

Saturable and dispersive parity-time symmetric directional coupler: a transmission-line modelling study (2014)
Conference Proceeding

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

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.
