1550nm Integrated Optic Chips IOCs-1550

 

1.      Applications

It is for attitude control of movements such as aircrafts, ships, guided missiles, automobiles etc in the fiber gyroscope system, Hydrophone and other optic sensitive fields. Faraday Effect was used to measure current through fiber circuit in the current sensing system. 

2.      Features: 

X-Cut, y-propagating LiNbO3

Very low insertion loss.

APE process for waveguide, works in single polarization

High extinction ratio

Fiber is sloping coupled with waveguide, which deduce optical return far and away

Push-pull electrode design may deduce half wave Voltage

Small packaging and lightweight

Excellent long-term stability
