-channel comb filtering and lasing in -symmetric superstructures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
A comb spectrum generating device based on Bragg grating superstructures with gain and loss is suggested in this paper. It includes a comprehensive analysis of the device formulati…
Phase shifted -symmetric periodic structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We report the spectral features of a phase-shifted parity and time ()-symmetric fiber Bragg grating (PPTFBG) and demonstrate its functionality as a demultiplexer in t…
Tailoring inhomogeneous -symmetric fiber Bragg grating spectra
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
The unique spectral behavior exhibited by a class of non-uniform Bragg periodic structures, namely chirped and apodized fiber Bragg gratings (FBGs) influenced by parity and time re…
Nonlinear nonuniform -symmetric Bragg grating structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We explore the consequences of incorporating parity and time reversal () symmetries on the dynamics of nonreciprocal light propagation exhibited by a class of nonunif…
Multifaceted dynamics and gap solitons in -symmetric periodic structures
S. Vignesh Raja, A. Govindarajan, A. Mahalingam +1
We report the role of -symmetry in switching characteristics of a highly nonlinear fiber Bragg grating (FBG) with cubic-quintic-septic nonlinearities. We demonstrate…
