In this paper, we present two possible architectures for wavelength division multiplexing–time division multiplexing hybrid long-reach passive optical network (PON) using reflective semiconductor optical amplifier (RSOA). We introduce both the upstream and downstream connectivity along with complete description of their working principles and implementation(More)
The presented paper is based on a new technology, QCA (Quantum-dot Cellular Automata), a promising successor for CMOS transistor technology. The implementation of logic circuits by the traditional devices (eg. transistors, diodes and resistors are replaced by quantum devices (quantum dots or single domain nano magnets). The use of quantum-dots is a(More)
The use of Reflective Optical Network Unit (ONU) in Passive Optical Networks (PON) is a very recent trend. This makes the ONU "colourless" and invokes an inherent physical layer security. A popular device of choice to implement the same is Reflective Semiconductor Optical Amplifier (RSOA). This paper presents a novel steady-state model of RSOA, along with a(More)
