Nonlinear characterization of Ge₂₈Sb₁₂Se₆₀ bulk and waveguide devices.
Single-mode Ge₂₈Sb₁₂Se₆₀ strip waveguides, fabricated with thermal evaporation and lift-off, were demonstrated at 1.03 µm. The linear and nonlinear optical properties of these waveguides were shown to be similar to bulk samples, with differences attributed to small variations in composition of ~4 atomic % or less. From z-scan measurements at 1.03 µm using circularly polarized, ~200 fs pulses at...

متن کاملMagneto-inductive waveguide devices
Devices formed from magneto-inductive waveguides based on coupled loop resonators are considered using simple analytic theory, initially assuming lossless propagation and nearestneighbour coupling. Two-port devices that were considered include mirrors, Fabry–Perot resonators, Bragg gratings and tapers, while more general N-port devices include power splitters and directional couplers. Condition...
متن کاملNon-Magneto-Optic Waveguide Isolator
We report on a novel technique to realize a waveguide optical isolator without using conventional magneto-optical materials and external magnets. The simulations are repeatedly performed using Beam Propagation Method (BPM) to confirm the accuracy. The simulation results show that the forward and backward propagations reach 2.54 and 15.68 dB, respectively.
متن کاملUsing of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser
Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...
