A dual optical time domain reflectometry (OTDR) system, which employs two different continuous waves at the optical line terminal and a pair of fiber Bragg gratings at the end of each optical network unit, is proposed in a time-division multiplexing passi
Several results on optical-axis perturbation and elimination of the mismatching error C of a monolithic triaxial ring resonator (MTRR) are reported. Based on the augmented 5£5 ray matrix method, by simultaneously considering axial displacement of a mirror
Cubic silicon carbide (SiC) nanowires are synthesized in a catalyst-assisted process. The nanowires with diameter of ~40 nm exhibit strong blue light emission at room temperature under ultraviolet (UV) femtosecond laser excitation. The photon energy of pe
