Fiber Couplers

The fiber couplers allow a direct diode fiber coupling of single emitters with only one lens element. The couplers consist of a monolithic glass block with two opposite crossed cylindrical surfaces and passive alignment edges. The light of the fast and slow axes is collimated by one cylindrical lens to produce a symmetrical focus.
