An amplifier covering the full C-band has been operated with an output
power of +33 dBm, owing to a new pump design incorporating 100-mm diodes coupled into the 50-mm multimode core of the amplifying
fiber.

An automated assembly technique for small
optical components has been developed. It concerns components such as, e.g.,
laser diodes and LEDs, fibers, lenses, beamsplitters, polarizers, mirrors,
crystals, prisms, diffractive elements or photodiodes. It is based on the
flexible 2-dimensional arrangement of an universal tripod holder (10 x 10 x 4
mm) on a planar mounting plate. Its particular mechanical structure allows to
align the optical elements on-line and to attach them to the mounting plate in
a one step procedure.
The different elements are aligned with an
accuracy of ±1 mm and attached one
after the other. Very good position stability (±0,7 mm, ±0,2 mrad) during the attachment procedure has been
achieved by laser point welding. They are optically interconnected by
free-space propagation of a light beam with a diameter of up to 8 millimeters.
Mass production has been shown with a collimator
as test vehicle. The collimator is composed of two elements (laser diode and
collimating lens) and is mounted entirely automatically by two co-working
robots. Easy prototyping has been shown with the realization of the optical
position sensing system featuring a high precision linear magnetic bearing.
Flexibility, simple handling, high packaging
density and low cost make this new assembly technique suitable to both mass
production and protoyping of small opto electronical devices.

A standardized optical mount based on a symmetric tripod structure has
been developed for an automated assembly procedure. It allows to achieve
submicron positioning accuracy and a beam pointing stability of 27 ± 70 µrad.
