Passive Components


GPCs' motorized variable optical delay line provides precision optical path length adjustment of up to 560 ps, single-pass. Driven by a DC motor with an integrated encoder, the MDL-002 has a resolution of less than 0.3μm (1 fs).

General Photonics’ motorized variable optical delay line provides low cost, precision optical path length adjustment and delay scanning functionality. This addition to the MDL product line is specifically designed for OEM applications that require continuous scanning capability and a small footprint.

AOI-Transceiver

AOI is a leading manufacturer of optical semiconductors for demanding analog and digital transmission systems. The portfolio includes analog optical components, digital optical components and optical data transceivers.

GPCs alle Festkörperpolarisationsschalter können die SOP des einfallenden Lichts schnell und wiederholbar um einen festen Winkel, entweder 45 oder 90 Grad, drehen. Sowohl Single-Mode- als auch PM-Faser-Pigtailed-Versionen sind verfügbar.
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.
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.

GPC-CS-DGD/PDL/SOPMD

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.
The polarization maintaining filter coupler can either split the light from an input PM fiber between 2 output PM fibers, or can combine light signals from 2 PM input fibers into a single PM output fiber.
