Accurate measurement of scattering and absorption loss in microphotonic devices
Matthew Borselli, Thomas J. Johnson, Oskar Painter
We present a simple measurement and analysis technique to determine the fraction of optical loss due to both radiation (scattering) and linear absorption in microphotonic component…
Surface Encapsulation for Low-Loss Silicon Photonics
M. Borselli, T. J. Johnson, C. P. Michael +2
Encapsulation layers are explored for passivating the surfaces of silicon to reduce optical absorption in the 1500-nm wavelength band. Surface-sensitive test structures consisting…
An optical fiber-taper probe for wafer-scale microphotonic device characterization
C. P. Michael, M. Borselli, T. J. Johnson +2
A small depression is created in a straight optical fiber taper to form a local probe suitable for studying closely spaced, planar microphotonic devices. The tension of the "dimple…
