In analysis of a new technique for quantum key distribution using the entangled photon within a micro ring resonator is presented. The Kerr nonlinear effects type of light circulates in the micro ring resonator is induced into the device. The superposition i.e. four-wave mixing of the propagating waves at resonance is occurred, where the entangled photon is generated. The possible two entangle pairs is described and discussed. The proposed system has shown the potential of using in the realistic system, where such a device scale can be fabricated and performed within the mobile telephone hand set, which means the use of quantum telephone will be realized in the near future.

Micro-ring resonators (MRRs) are employed to generate signals used for optical communication applications, where they can be integrated in a single system. These structures are ideal candidates for very large-scale integrated (VLSI) photonic circuits, since they provide a wide range of optical signal processing functions while being ultra-compact. Soliton pulses have sufficient stability for preservation of their shape and velocity. Technological progress in fields such as tunable narrow band laser systems, multiple transmission, and MRR systems constitute a base for the development of new transmission techniques. Controlling the speed of a light signal has many potential applications in fiber optic communication and quantum computing. The slow light effect has many important applications and is a key technology for all optical networks such as optical signal processing. Generation of slow light in MRRs is based on the nonlinear optical fibers. Slow light can be generated within the micro-ring devices, which will be able to be used with the mobile telephone. Therefore, the message can be kept encrypted via quantum cryptography. Thus perfect security in a mobile telephone network is plausible. This research study involves both numerical experiments and theoretical work based on MRRs for secured communication.
