Abstract: Optical fibers are widely used in communication and information systems. This needs studying the factors that affect signal quality. In this work and optical fibers having two different laser beams passing through it were exposed to heat by raising temperature from 30°C to 50°C in steps of 2°C. The empirical relation shows linear increase of attenu... Show More

Abstract: Cu₂O nanowires (Nws) network-based heterojunction was observed to have a position-sensitive photovoltaic characteristic. Its amplitude of the photovoltage (V_ph) varied regularly with the position of incidence of the 532nm laser radiation onto the Cu₂O NWs surface. The V_ph of this platform varies with the light position described as ∆V_ph/∆x is appro... Show More
