Emcore Introduces Fiber Optic Gyro Modules

Emcore Corp., a provider of compound semiconductor-based components and subsystems for the fiber optics and space solar power markets, has released the new EMP-3, EMP-4, and EMP-7 fiber optic gyroscope (FOG) modules, expanding the company's EMP FOG platform with the latest generation navigational grade fiber optic gyro technology.

 

The EMP-3, EMP-4 and EMP-7 augment Emcore's FOG product line between the tactical grade EMP-1 and the navigational grade EMP-1.2K. The latest models feature performance specifications for medium-accuracy platform stabilization applications such as camera systems used in aircraft and Unmanned Aerial Vehicles (UAVs), as well as a variety of other guidance, navigation, and aeronautics applications. The availability of these new navigational grade models provides customers with greater flexibility to choose the performance parameters that best meet their application.

 

The latest EMP-3, -4, and -7 FOG modules operate over a broad distance range with a typical bias drift from 0.2° per hour for the EMP-3, to a mere 0.005° for the EMP-7. Bias drift is an important measure of accuracy and precision of the FOG, with lower-bias models delivering higher performance overall. According to the company’s press release, the EMP-3, EMP-4 and EMP-7 feature advanced integrated optics and closed-loop digital signal processing (DSP) electronics to deliver higher accuracy, lower noise, greater efficiency, improved drift stability, and higher linearity than competing technologies.

 

Emcore develops most of the key FOG components internally, including the optical transceiver and the lithium-niobate modulator. This allows performance parameters to be customized to specific customer requirements.
