In this paper, the bifurcation behavior of light in the PANDA ring resonator is investigated using the signal flow graph (SFG) method, where the optical transfer function for the through and drop ports of the PANDA Vernier system are derived. The optical nonlinear phenomena, such as bistability, Ikeda instability, and dynamics of light in the silicon-on-insulator (SOI) PANDA ring resonator with four couplers are studied. The transmission curves for bistability and instability as a function of the resonant mode numbers and coupling coefficients for the coupler are derived by the SFG method and simulated. The proposed system has an advantage as no optical pumping component is required. Simulated results show that closed-loop bistable switching can be generated and achieved by varying mode resonant numbers in the SOI-PANDA Vernier resonator, where a smooth and closed-loop bistable switching with low relative output/input power can be obtained and realized. The minimum through-port switching time of 1.1 ps for resonant mode numbers of 5;4;4 and minimum drop port switching time of 1.96 ps for resonant mode numbers of 9;7;7 of the PANDA Vernier resonator are achieved, which makes the PANDA Vernier resonator an operative component for optical applications, such as optical signal processing and a fast switching key in photonics integrated circuits.

“…n e f f is the effective refractive index of the waveguide, and the L = 2π R is the perimeter of the ring with the radius of R. The free spectral range (FSR) of the device is determined by F S R i = c/(n g L i ) where n g = n ef f + f 0 (dn ef f /d f ) f 0 is the group refractive index of the ring, n e f f is the effective refractive index, and f 0 is the design (center) frequency [7].

Nonlinear response of light such as bistability, the Ikeda instability and the dynamics of light within InGaAsPInP-modified add-drop resonator (PANDA Vernier resonator) is studied. The signal flow graph method is used to obtain the optical transfer function. Invariant and symmetric coupling coefficients k R = k L = 0.25 for indirect couplers are applied and the effect of changing symmetric direct couplers ( K 1 = K 2 ) for two different resonant mode numbers is studied. The minimum drop port switching time of 2.83 ps and 2.87 ps for resonant mode numbers of 7;5;5 and 4;3;3 are achieved, respectively. The simulated results introduce the PANDA Vernier system as a proper optical device for future optical communication and signal processing systems.Index Terms-Optical switching, bistable switching, PANDA vernier filter, optical bistability.

The optical transfer function is derived for add-drop resonator (ADR) using the signal flow graph method. A critical coupling condition is calculated in the presence of loss in the coupling regions. Effect of critical coupling and coupler loss in the light transmission is studied. A limited area was determined for optimum optical transmission of ADR. We introduced a semi-empirical equation to correlate the geometric design of coupling gap with the coupling strength parameters (coupling coefficient, k, and coupling loss, γ). Achieved results can be used in optical communication technology and the photonic sensor applications.
