Packaging
and demonstrators
In order to assess
device and
circuit performances and to provide application teams with functional
devices, packaging is a key technology for the III-V Lab.
Packages are first
designed taking
into account the specific thermal and electromagnetic requirements of
the application. Using conventional Au wire or ribbon bonding, devices
are packaged using thin film substrates with chip capacitors and
resistors.
Optical coupling
generally uses lensed fiber or micro-optics, with YAG welding for final
assembly.

Lensed fibres are used in this Electro-Absorption Modulator module, operating at 40 Gbit/s (eye diagram below)
