SINGLE-MODE COUPLERS
Fiber optic couplers used split light from fiber into with excess loss backreflection. Couplers also combine signals from fibers into one. larger distribution schemes, couplers cascaded creating input output) configurations.These components generally used signal distribution, light monitoring, measurement applications.
TECH NOTE
Wave Optics' Couplers. offer fused couplers standard single-mode fibers well shorter wavelength specialty fibers. couplers available bare fiber ruggedized packaging.These passive devices manufactured using fused biconical taper method. this process, fibers twisted, heated, pulled. pulling continues, with output fibers actively monitored, until correct split ratio achieved.The fused fibers then environmentally sealed. Wave Optics'
fused single-mode couplers exhibit superior thermal, shock, vibration characteristics well wide operating range. Because fibers never broken fused couplers, backreflection remains very (<-55 making them ideal backreflection measurements (see page 18).

PLANAR WAVEGUIDE COUPLERS
Planar waveguides integrated optic devices containing pattern generated photolithographic process.The result highly uniform,repeatable device with wide operating wavelength range. Wave Optics combines these devices with aligned silicon V-groove arrays (see page 32), pigtailing, packaging techniques create planar waveguide couplers. Conventional methods
cascading fused couplers become complicated unpredictable stress patterns generated each fusion junction.The advantage planar waveguide couplers especially evident configurations. Wave Optics manufactures these couplers with panda fibers, with fast slow axis alignment.

POLARIZATION BEAM SPLITTER/COMBINER
Wave Optics offers pigtailed polarization beam splitter. polarization splitter combiner) splits light signal into orthogonal linearly polarized signals. Signals combined reversing their paths back into crystal. beam splitting element birefringent crystal.The splitter works taking advantage anisotropic structure this crystal; that crystal does have same optical density transverse propagation vectors. When randomly polarized signal passed through crystal this kind polarization broken into components relative optical orientation crystal. Both beams will emerge linearly polarized,but with polarization orientations perpendicular each other.
TECH NOTE
Wave Optics' splitter/combiner designed maximum coupling efficiency, stability, extinction ratio. optical surfaces anti-reflection coated peak wavelength specified, fiber ends angle polished. Since these components combine light through free space beam, they also used power combiners, unlike conventional fused couplers (see page 38). This splitter/ combiner also much higher power capability than common waveguide devices making ideal higher power applications. devices delivered with panda fiber ruggedized housing.
BIREFRINGENT CRYSTALS
Only certain types crystals will exhibit birefringent behavior. Crystals must have hexagonal,tetragonal,or trigonal lattice structures allow light encounter asymmetric structure.Some common materials with these characteristics calcite (calcium carbonate),quartz,and tourmaline.There many ways make beam splitter cube from these materials, most common being slicing rectangular prism material along diagonal,and cementing back together different orientation.

PLUG STYLE ATTENUATORS
Wave Optics' doped-fiber attenuators male-to-female assemblies used reduce optical power transmitted through fiber. most common uses include equalizing power between fibers multifiber systems reducing receiver saturation, which limit system performance. These "plug-style" attenuators work small section doped fiber placed in-line with female male sides device.The dopant transition metal internal fiber, which absorbs optical energy predictable gradual way, gradually disperses energy heat.The metal appears opaque light operational range, continually reduces power along its' length.The fiber also quite durable, withstanding 100-hour exposure
tests light, with variation attenuation only ±0.1 dB.The polarization dependent loss (PDL) generally believe that capabilities this type fiber, together with convenience plug style, allow attenuators achieve performance superior that regular filter-style attenuators. Filter based products reduce power single point limiting power handling capability. This type attenuation also tends have higher wavelength dependence limiting operational wavelength range.
