Abstract: (2175 Views)
Todays, tunable optical integrated circuits play an important role in all-optical processors. In this paper, design and full-wave analysis of a tunable optical fractional-order temporal differentiator based on microring resonator have been presented. Applying forward and reverse bias voltages to the microring resonator based on P-I-N and P-N junctions and free carrier dispersion effect causes to change in the effective refractive-index, operating regime of the microring resonator and the order of differentiation; thus, the tunability of the circuit has been realized. The desired performance of the designed tunable optical differentiator has been confirmed considering an ultra-fast Gaussian input pulse with temporal FWHM of 6.3 ps.
Keywords: Tunable differentiator, Fractional order differentiator, Microring resonator, Signal processing, Free carrier dispersion.
