Fiber Optics

The MZI-001 is a fiber pigtailed compact Mach-Zehnder interferometer, based on freespace optics, for detecting changes in optical frequency. The device comes with two fast photodetectors for the balanced detection of the two complementary outputs of the interferometer.

This patented device comes in a package as small as 85 × 60 × 10 mm for lasers with coherence lengths less than 10 meters. Devices for coherence lengths in the kilometer range can be custom made in a larger package, with nominal customization fees.

PMD and PDL are important considerations in many applications, especially high data-rate communications. With the development of high precision test equipment and tighter-tolerance systems, a need has arisen for extremely precise calibration standards.

GPCs’ fixed differential group delay lines eliminate the need for precise measurement of PM fiber lengths to add defined amounts of first order PMD to a system.

A suite of advanced polarization test instruments specially designed for testing the quality of fiber coils ensures the consistent production of high performance coils. GPCs' PM coils can be wound with different winding patterns such as quadrupole, octupole, or other types to minimize the Shupe effect, which degrades the performance of a fiber gyro under temperature-varying conditions.

The Faraday rotator mirror is a fiber optic polarization rotation mirror designed for fiber optic networks and measurement applications. The state of polarization (SOP) of the reflected light is rotated 90 degrees from that of the input light.

These isolators are the smallest in size but the highest in quality in the market. They are ruggedly built to function reliably in a wide variety of environments.

InsideView(TM) is an optical coherence domain reflectometer (OCDR- 1000) designed to obtain space-resolved reflection information inside a fiber optical component, such as a Photonic Integrated Circuit (PIC), for diagnosing quality or design issues.
