Single-Mode Fiber Coupler
The single-mode fiber coupler DY-05A achieves effective single-mode coupling of a laser beam into a bare single-mode fiber.; Provides the sub-micron positioning resolution required for high single-mode coupling efficiency.; Fine translation and focusing to position the focused laser beam on the fiber end face are provided by a three-axis positioner: M5x0.25 adjustment screws for smooth XY adjustment and a knurled knob with M16x0.75 thread for Z axial motion.; The sub-micron resolution needed to optimize coupling into a single-mode fiber is provided by a dynamic tilt stage that rotates the lens/fiber holder assembly using M5x0.25 adjustment screws.; Unlike conventional couplers whose positioner run-out may exceed the fiber misalignment tolerance, the fine tilt adjustment introduces only second-order beam translation.; The coupler’s optical axis height is fixed at a nominal 76 mm, with threaded and through holes on the base for easy mounting on platforms and breadboards.
Product Introduction
DEYU is a professional manufacturer of fiber coupling systems offering precision fiber couplers of excellent quality, including multi-mode fiber coupling stages, NxN coupling systems, waveguide reflection systems and automatic fiber coupling equipment. Single-mode fiber coupling differs from multi-mode coupling mainly in that Gaussian beam mode matching must be considered. The single-mode fiber coupler DY-05A achieves effective single-mode coupling of a laser beam into a bare single-mode fiber, and provides the sub-micron positioning resolution required for high single-mode coupling efficiency.
