  We report on our latest developments of a planar fiber-chip-coupling scheme,
using angle polished, polarization maintaining (PM) fibers. Most integrated
photonic chip components are polarization sensitive and a suitable way to
launch several wavelength channels with the same polarization to the chip is
the use of PM fibers. Those impose several challenges at processing and
handling to achieve a stable, permanent, and low-loss coupling. We present the
processing of the fibers in detail and experimental results for our planar and
compact fiber-chip-coupling technique.
