We demonstrate single-mode ZBLAN optical fiber couplers. A controlled tapering procedure leads to coupling ratios of 5%/95% and 14%/86% at a wavelength 2200 nm, with insertion losses 1.6 dB 1.8 dB, respectively.
In this article, hybrid composite laminates with shape memory alloy (SMA) and glass fiber (GF) as the reinforced phase, and epoxy resin as the host material, were manufactured by vacuum-assisted resin injection (VARI) processing. The SMA wires were embedded into the GF/epoxy composites with three kinds of modes. The effect of SMA content and the position on the flexural, low-velocity impact per...
A silicon Mach–Zehnder modulator with a low-loss phase shifter formed by restricted-depth doping is fabricated and characterized. The phase shifter has a PN junction at the bottom of the rib waveguide, whereas the top of the rib is un-doped. Device simulations confirm that the phase-shifter loss is reduced by 26−28% with an increased phase-shifter length to keep a π phase shift with the same bi...
To accurately determine sample optical properties using single fiber reflectance spectroscopy (SFR), an absolute calibration of the reflectance is required. We investigated two SFR calibration methods, using a calibrated mirror and using the Fresnel reflection at the fiber tip as a reference. We compared these to commonly used calibration methods, using either Intralipid-20% in combination with...
