Cladding light strippers encapsulate fiber splices to remove stray cladding light, reducing splice loss, overheating, and beam degradation.

Index-matched cladding stripping at fiber splices removes stray light and conducts heat away to protect high-power beam combiners.

A single pump source and optical coupler feed two amplification stages in laser radar, cutting optical parts, size, power use, and control complexity.

Spiral transverse notches let cladding light escape gradually into a heat sink, reducing hot spots while preserving core light quality.

An intermediate-index resin in the coating-removed section confines light, reducing secondary-coating heating and improving fiber reliability.

A third cladding confines return light inside input fibers, reducing heat buildup from absorption and improving laser system reliability.

Selective coupling into the inner or outer ring core of a multi-clad fiber changes laser beam profiles without added source complexity.

A bridge fiber and intermediate fiber combine lasers into center and ring cores without fiber thinning, improving strength and beam-profile control.

A two-region core and lower-index trench cut bending loss while limiting trench reflection that degrades short-distance POF bandwidth.

Rounded polygonal inner cladding with controlled angularity and twist redirects pump light into the core to suppress skew modes and cut loss.

A tapered large-core to small-core fiber raises damage threshold while enabling broad, high-power supercontinuum generation.

Adiabatic etching and tapering match core modes and cladding sizes, cutting insertion loss while preserving high-power cladding light.

Encapsulating a multi-clad fiber splice with cladding light strippers removes stray cladding light, limiting hotspots and beam defects.

A high-peak pulse laser boosts plasma light during continuous laser processing, enabling more accurate monitoring of process conditions.

A multi-core fiber combines center and ring beams to cut thick metal with cleaner kerfs, fewer surface irregularities, and less self-burning.

Variable core-ring and leading-trailing beam splitting improves full-penetration laser weld quality while reducing spatter and humping.

Dynamic center and ring beam power control improves thick metal cutting quality, reducing self-burning and kerf instability at turns.

A multi-clad plastic optical fiber uses tuned resin layers to maintain bandwidth, low loss, and bend durability after long heat exposure.

A trench layer with tuned volume and refractive index lets multicore fiber shrink cladding diameter while limiting crosstalk and confinement loss.

Different core index profiles and 20-50 μm spacing suppress crosstalk while keeping group velocities aligned for synchronized transmission.

Using high-purity silica only near the core and lower-purity outer cladding cuts soot waste and raw material cost without harming fiber quality.

An SMP layer on an LCE-clad optical fiber enables reversible bending, redirecting light at varying angles with low attenuation.

Combining a Faraday rotator with a quarter- or half-waveplate enables different polarization changes for forward and reverse light paths.

Different core groups with 10%+ area or cutoff variation suppress inter-core crosstalk while keeping a practical 125 µm fiber diameter.

Distinct core groups with different effective areas and adjacent-group placement suppress inter-core crosstalk while keeping a practical 125 μm fiber diameter.

A W-shaped refractive index profile balances large effective core area with single-mode operation, low bending loss, and short cable cut-off wavelength.

A down-doped peripheral cladding layer cuts leakage and micro bending loss while keeping multicore fiber crosstalk below -30 dB.
