Ultrafast optical switching using parity-time symmetric Bragg gratings (2013)
Journal Article
Phang, S., Vukovic, A., Susanto, H., Benson, T. M., & Sewell, P. (2013). Ultrafast optical switching using parity-time symmetric Bragg gratings. Journal of the Optical Society of America B, 30(11), https://doi.org/10.1364/JOSAB.30.002984

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....
