Abstract

In this paper, we discuss the simulation results of a ripple-corrected bandpass filter of a Non-cascaded Multifunctional Optical Filter (MOF) Ciruit. The MOF circuit is a Mach Zehnder Interformeter (MZI)-based circuit wherein Cross (C-APF) and Direct (D-APF) Coupled All-Pass Filters are attached across the circuit MZI arms. Our findings suggest that the ripples of the passband and stopband regions can be controlled by the (a) ring resonator and (b) delay line phase differences of the circuit. This has been verified analytically and through numerical simulation using the Finite Difference Time Domain Solver of Lumerical MODE.
