We have studied the effect of duty cycle variation in the Fibonacci optical superlattice (FOS) structure by analysing the second harmonic generation (SHG) spectrum. Unlike periodic quasi-phase matc...

We investigate the effect of phase shifter domains to generate multiple Second harmonic Generation (SHG) response in a single channel QPM device. Phase shifters are the domains capable of changing phase of the interacting wave in the medium from 0 to

Thue-Morse is a quasi-periodic sequence that can be used in optical super lattices to generate multiple-Quasi-Phase Matching (QPM) profiles because it has number of reciprocal vectors in its structure. However, it results in randomized peaks. In orde

We have analyzed the simulated annealing algorithm in a Fibonacci based optical superlattices to obtain multiple second harmonic generation (SHG) in a single channel Quasi-Phase matching (QPM) device. The Fibonacci sequence itself has plenty of recip

We have utilized the general algorithm of simulated annealing (SA) to engineer the phase shifter domains in a quasi-phase-matching (QPM) device to generate multiple frequency conversion. SA is an algorithm generally used to find the global maxima or
