Optical properties of photonic crystal fiber with integral micron-sized Ge wire.
- H. TyagiM. SchmidtL. SempereP. Russell
- 27 October 2008
Engineering, Materials Science
Since Ge provides electrical conductance together with low-loss guidance in the mid-IR, Ge-filled PCF seems likely to lead to new kinds of in-fiber detector and sensor, as well as having potential uses in ultra-low-threshold nonlinear optical devices.
Analytic model for the complex effective index of the leaky modes of tube-type anti-resonant hollow core fibers
- M. ZeisbergerM. Schmidt
- 18 September 2017
Engineering, Physics
A model that approximates, using the reflection of a wave on a single planar film, modal guidance in tube-type anti-resonant waveguides whose core diameters are large compared to the wavelength is introduced.
Supercontinuum generation in a carbon disulfide core microstructured optical fiber.

- 21 June 2021
Physics, Materials Science
The presented results demonstrate an extraordinary high conversion efficiency from pump to soliton and to dispersive wave, overall defining a platform that enables studying the impact of non-instantaneous responses on ultrafast soliton dynamics and coherence using straightforward pump lasers and diagnostics.
All-solid bandgap guiding in tellurite-filled silica photonic crystal fibers.
- M. SchmidtN. GranzowN. DaM. PengL. WondraczekP. Russell
- 1 July 2009
Engineering, Materials Science
All-solid bandgap-guiding fibers formed by pumping molten tellurite glass into silica-air photonic crystal fiber at high pressure offer a potential route to employing difficult-to-handle glasses, or glasses unsuitable for fiber drawing, in fiber-based amplifiers, modulators, filters, and nonlinear devices.
