SCALING OF OPTICAL LOGIC DEVICES AND ARRAYS

Le Journal de Physique Colloques, 1988
The use of ion-beam-assisted etching to form ~ 1.5-µm diameter waveguiding "posts", or microresonators, in a GaAs/AlAs Fabry-Perot structure grown entirely by molecular beam epitaxy has reduced the device cross-sectional areas, energy requirements and recovery times all by more than an order of magnitude1.
