Description:
ASML Navaigation's MIOC-S chip is a key component in Fiber Optic Gyroscope (FOG) for measuring angular velocity of an inertial navigation system. This integrated device, fabricated on Lithium Niobate (LiNbO3) material, is composed of a polarizer, a Y-junction coupler and dual electro-optical phase modulators. Waveguides on the chip are produced by the High Temperature Proton Exchange (HTPE) process. The MIOC-S has more than 60dB Polarization Extinction Ratio (PER) and can minimize bias drift resulting from
polarization crosstalk induced non-reciprocity. This MIOC-S device has been used in a high-sensitivity inertial navigation system to detect less than 0.5 deg/hour angular velocity change. It has highly reliable performance with wide temperature range tolerance.

Operation Instructions
a). If the devices work under the single state of polarization, the polarization state of input light must conform to devices.
b).Avoid the Electrical damage of the devices; the electrode voltage of modulators should be lower 30V.
c) .Applying too much force to fiber may cause it broking easily. Avoid drawing、twisting.Bending radius must not be less than 30nm.
d) Avoid too much force between metal tube and fibers. Put up the tube and the fibers together when using it. Avoid bending at the joint of the tube and the fibers.
e) Storage environment humidity must be less than 50%, and not contain the materials which damages devices.
f) Avoid the devices suffering from intense thermal shock and inhomogeneous by heated
g) Avoid stressing to the joint of the fiber connection circuits.
