Double-Clad Fiber Couplers (DCFC)

Double-Clad Fiber Optic Coupler/Splitters for Confocal Microscopy, Scanners, Fluorescence Imaging,  Spectrally Encoded Endoscopy, Spectroscopy, Optical Coherence Tomography (OCT), LIDAR, Surface Plasmon Resonance (SPR), and more...

Two types of double-clad fiber couplers are available:

Type 1: Symmetric Double-Clad Fiber Couplers (S-DCFC), fabricated from double-clad fibers (DCF) with identical core and inner/outer cladding diameters.

Type 2: Asymmetric Double-Clad Fiber Couplers (A-DCFC), fabricated from double-clad fibers (DCF) and multimode/large core fibers (100um, 200um, 300um cores) with different core/cladding diameters, can be custom designed for optimizing coupling into the multimode fiber.

- Single mode (SM) core for 450nm to 1632nm wavelengths

- Inner cladding diameters 15um to 105um

- High coupling ratio to inner cladding or to multimode fiber, up to 60%. Custom coupling ratio available upon request.

- Low back refection

- Low loss for SM core signal, < 0.3dB.

- Low loss for inner cladding signal.

- Custom fabrication, please call us for custom designs.
