Model:
MIOC******-XX-N
The main fiber optical
gyroscope's components is a multifunctional integrated optical chip
(MIOC). FOGPhotonics's MIOC is a solid state waveguide device on
X-cut LiNbO3 substrate fabricated by high-temperature proton
exchange method (HTPE). A very important advantage of proton
exchange (PE) waveguides is the following. In such waveguides the
extraordinary refraction index is increasing, while refraction
index of ordinary ray is decreasing. As a result, proton exchanged
waveguides support propagation only extraordinary polarization
modes (TE in our case). Therefore, it is not necessary to use in
the fiber optical gyroscope a polarizer, which brings additional
loss.
To meet the requirements for
defect-free edge polishing of high precision fiber optic gyroscope
integrated optic modulator LiNbO3
chips, a new
polishing process based on pad polishing was developed. According
to the analysis on the causes for edge damage during the
edge polishing,
three solutions were presented:controlling the big particles in
polishing material, choosing the low subface damage polishing
and making
the particles size close to or less than double of the critical
cutting depth. With the new process,the defect free edge
polishing of LiNbO3 chips
could be achieved and the results show that the edges under 1 **0×
microscope have no visible defect, the chip end face roughness
Ra is less
than 0.8 nm and the surface flatness reaches better than
λ/2.Additional,this polishing process has great application
value.

Operation
Instructions
a). If the devices work under the single
state of polarization, the polarization state of light must
conform to devices.
b).Avoid the Electrical damage of the
devices; the electrode voltage of modulators should be lower
*0V.
c) .Applying too much force to fiber may
cause it broking easily. Avoid drawing、twisting.Bending radius must
not be less than *0nm.
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 *0%, 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.
