This technology is centered around development of all optical approach for computing and communication purpose. The end goal is a photonic processor, which uses the photons of visible light rather than electric current to perform digital computations. On order to achieve this, digital design needs to be done in optics. This technology provides an optical digital logic gate library consisting of NOR, OR, AND, XOR, and two compound gates. Further, included are modulators, switches, and oscillators. These gates which are designed using semiconductor ring lasers (SRL) are analyzed and modeled by developing rate equations. This digital library can be used in any CAD tool developed to design integrated photonics components. The distinctive advantages of using micro ring lasers for the design of logic gates include low power consumption and compatibility to be mounted on to a single photonic IC.
