“…The optical pulse circulate into the modified ring will split at coupled (κ 2 ) into the straight waveguide (medium) and output to drop port as shown in Figure 1. The optical fields transmitted and circulated in modified add-drop filter can be written as [19,20,21,28]. The mathematic model for optical field output of the modified add-drop filter at through port (E t1 ) as shown in equation (1).…”

Optical micro-ring resonators (MRRs) element can be used in many applications. This paper we propose a photonics circuit design based on optical tree architecture (OTA) for all-optical elements by using the modified add-drop filter for an all-optical arithmetic logic unit (ALU) aimed for computing applications system. All-optical 2x4 decoder, all-optical comparator, all-optical half adder, all-optical half subtractor, all-optical full adder, all-optical full subtractor and proposed new design all-optical 4x16 decoder were proposed. We have studied the nonlinear effect in the modified add-drop filter system, which is control by injected the nonlinear pulses on top as an input for generated all-optical logic and arithmetic operations simultaneously at the through and drop port of modified add-drop filter. The optical input and control field of the modified add-drop filter circuit can be formed by nonlinear dark and bright pluses. The obtained simulation results have shown that the nonlinear pulse generated by the nonlinear modified add-drop filter can control the output consistency, which is important when the interconnect between each circuit output parts are required. The advantages of the modified add-drop filter are low power, ultra-fast switching, tuneable and high security which is compact size and footprint. It is suitable for the next generation of all-optical small-scale device and all-optical computing system requirements.

One of the critical problems in achieving a real practical all-optical switching devices is the requirement for a strong material nonlinearity. A strong material nonlinearity is crucial in order to achieve a low switching power. However, silicon-based all-optical switches require extremely high switching power due to its relatively weak nonlinear optical properties. To overcome this limitation, we have designed an all-optical switch configuration based on silicon microring resonator structure and demonstrated the switching operation based on the nonlinear effects induced by a soliton pulse. The soliton pulse induces freecarrier concentration through two-photon absorption (TPA) effect and this leads to enhance the refractive index change and enhance the nonlinearity of the silicon. Thus, the silicon microring resonator alters the nonlinear phase shift which is required for switching.
