This indicates pressing DANGER, and if it
is not avoided, personnel death or serious
injury may result; therefore, it is the most
emphasized special information.
This indicates potential danger, and if it is
not avoided, personnel death or serious
injury may result; therefore, it is special
information.

Introduction
1
The PCU-110 is a polarization state generation device. This device is capable of
generating 6 special states of polarization (SOP) across the Poincare sphere: linear
polarization states at 0°, +90°, +45°, and –45° as well as right hand circular (RCP)
and left hand circular (LCP) polarization states, relative to the axis defined by an
internal linear polarizer. The actual output polarization states may be rotated due to
the output single mode ber, so the exact SOP locations on the Poincaré sphere of
the Polarimeter may be different. However, the 6 generated polarization states will
symmetrically cover the Poincaré sphere with the same angular relationship.
