SelenOptics specializes in the development and fabrication of Chalcogenide fibers and proposes several standard infrared fibers with light propagation in the 1.5 to 10 µm wavelength range. SelenOptics can customize the design of its infrared fiber specifications: including single-mode vs. multimode fiber, polarization-maintaining (PM) or standard, core diameter, numerical aperture, dispersion profile, etc.

1.5 to 10µm Wide Bandwidth Single Mode Chalcogenide fibers
Single Mode (SM) Chalcogenide AsSe fibers combine great spatial beam quality over a broad spectral range, low optical attenuation and high non-linear refractive index compared to traditional silica fibers. These SM AsSe fibers with large transmission bandwidth in the mid-infrared region from 1.5 to 10µm can be used as efficient power delivery pigtail fiber in the packaging of quantum cascaded laser (QCL), optical parametric oscillator (OPO) or mid-infrared fiber systems.
Suspended Core “Grape-Fruit” AsSe Micro-structured Fibers
The multimode (MM) Grapefruit type (AsSe) Chalcogenide fibers have low transmission loss over a wide bandwidth of operation from 1.5µm to 9µm and large numerical aperture that allows easier light coupling into the fiber. Some MM Grapefruit fibers are available in stock, and can also be custom drawn to many different fiber geometries and specifications. These fibers can be used for efficient delivery or transmission of laser power.

Highly Nonlinear SM-MM GeAsSe and AeSe Chalcogenide Fibers
The single-mode Chalcogenide (GeAsSe) and multimode (AsSe) nonlinear fibers exhibit low propagation loss combined with low Brillouin threshold, and large fiber non-linearities, making them ideal waveguides for the novel designs of amplifiers and lasers in the Mid-IR spectrum. Examples of products include super broad continuum source (i.e. 1.5 to 10µm), wavelength generation via four-wave mixing and Brillouin and Raman fiber lasers and amplifiers. For specific applications, the fiber core (in the range from 3 to 7µm) and the zero-dispersion wavelength can be adjusted to optimize the fiber performance.
Fabrication of Fiber Devices: Taper & Connectorized Fiber Pigtails
SelenOptics has developed both fiber tapers for mid-infrared fibers and connectorized fiber jumper cables. The taper technology has been demonstrated and integrated in customer applications and this know-how can be customized upon customer requests. Fiber jumper cables with different lengths are terminated with standard FC/PC connectors. Other types of connectors are also available. These cables find their applications in the pigtailing of mid-infrared products (laser, modulators, switches, etc) and in the transmission of laser power to remote location with minimal optical degradation.
