One-Step Patterning of Asymmetric Gate Recess for InP HEMTs using Genetic Algorithms (2008)

Franck Robin, Andrea Orzati, Esteban Moreno, Michael Spühler, Otte Homan, Werner Bächtold

For the first time, a canonical genetic algorithm was used to optimize the resist profiles for T-gate fabrication. An e-beam lithography simulation tool was elaborated that calculates the...

Topological investigations on evolutionary optimized non- periodic optical structures (2007)

Michael Spühler, Daniel Erni, Jürg Fröhlich

In an earlier stage of this work two different non-periodic optical waveguide structures, such as a multi-cavity semiconductor laser diode and a non-periodic segmented mode converter have...

A generalized evolutionary optimization procedure applied to waveguide mode treatment in non-periodic optical structures (1998)

Daniel Erni, Michael Spühler, Jürg Fröhlich

Two different non-periodic optical waveguide structures, such as a multi-cavity semiconductor laser diode and a non-periodic segmented mode converter have been optimized using a generalized...
