Time-resolved reversible optical switching of the ultralow-loss phase change material Sb2Se3
Daniel Lawson, Daniel W. Hewak, Otto L. Muskens +1
The antimony-based chalcogenide Sb2Se3 is a rapidly emerging material for photonic phase change applications owing to its ultra-low optical losses at telecommunication wavelengths…
Fabrication and characterization of femtosecond laser written waveguides in chalcogenide glass
M. Hughes, W. Yang, D. Hewak
The authors describe the fabrication of buried waveguides in a highly nonlinear chalcogenide glass, gallium lanthanum sulfide, using focused femtosecond laser pulses. Through optic…
Enhanced Meta-Displays Using Advanced Phase-Change Materials
Omid Hemmatyar, Sajjad Abdollahramezani, Ioannis Zeimpekis +12
Structural colors generated due to light scattering from static all-dielectric metasurfaces have successfully enabled high-resolution, high-saturation, and wide-gamut color printin…
Towards low loss non-volatile phase change materials in mid index waveguides
Joaquin Faneca, Ioannis Zeimpekis, S. T. Ilie +4
Photonic integrated circuits currently use platform intrinsic thermo-optic and electro-optic effects to implement dynamic functions such as switching, modulation and other processi…
Non-volatile programmable silicon photonics using an ultralow loss SbSe phase change material
Matthew Delaney, Ioannis Zeimpekis, Han Du +5
Adaptable, reconfigurable and programmable are key functionalities for the next generation of silicon-based photonic processors, neural and quantum networks. Phase change technolog…
