The present work investigates the switching dynamics of conventional fiber Bragg gratings
(FBGs) with saturable coupling and parity-time (PT)-symmetric fiber Bragg gratings …

We report the role of PT symmetry in switching characteristics of a highly nonlinear fiber
Bragg grating (FBG) with cubic-quintic-septimal nonlinearities. We demonstrate that the …

We report the spectral features of a phase-shifted parity and time (PT) symmetric fiber Bragg
grating and demonstrate its functionality as a demultiplexer in the unbroken PT-symmetric …

Nonlinear optical switching is a prominent technology for high-speed data processing. All-

In recent years, the field of PT-symmetry has witnessed a surge of research interest due to its
ability to exploit even the losses of the system. PT-symmetry and its implications have been …

We explore the consequences of incorporating parity and time reversal (PT) symmetries on

In this paper, we perform a theoretical study of the all-optical logic gates based on the
techniques of cross phase modulation (XPM) in a phase-shifted grating. Here the pumps are …

We report that conventional saturable periodic structures, in sharp contrast to the
conventional systems with different nonlinearities which exhibit the typical S-shaped optical …

This paper is focused on modern optical switching, which is a subject of great interest due to
the high speed, secure data processing, and compact size of modern communication …

In the context of parity–time (PT)-symmetric fiber Bragg gratings, tailoring the nonlinear
profile along the propagation coordinate serves as a new direction for realizing low-power …
