POLARIZATION COMPENSATION SIMPLIFIED OPTICAL MEASUREMENT OPTICS

Improves measurement stability by polarization compensasion by arrangement of half mirror○Polarization compensasion simpliﬁed optical measurement optics M-Scope type J/PF
When using single mode optical ﬁber for introducing measurement light, polarization
state may changes inside the single mode ﬁber due to the inﬂuence of stress such as
bending applied to the optical ﬁber due to the inﬂuence of the external environment.
For this reason, the measurement accuracy of the entire system may become unstable
due to the polarization dependence of half mirror for splitter. M-Scope type J/PF is theoptics that realizes stable and highly accurate measurement by removing the inﬂuenceof polarization by arrangement of half mirror.

【Applied system of M-Scope type J/PF】Optical method insertion loss
measurement system for micro structural waveguide device
This is the system for insertion loss measurement of micro structural waveguide device
using M-Scope type J/PF. It realizes high-speed and accurate insertion loss
measurement of micro structural waveguide such as silicon photonics waveguides. By
combining optical ﬁber and coaxial observation imaging detector mounted on M-Scope
type J/PF, and motorized stage system, you can directly observe input and output
face and core of optical waveguide to be measured, and at the same time perform
power alignment by optical ﬁber. By using coarse alignment by image processing andﬁne alignment by optical ﬁber (optical power alignment), insertion loss measurementof micro structural waveguide can be performed at high speed and high reproducibility.
