Photonic Crystal Fiber Interfacing

Introducing PCF (Photonic Crystal fiber) often gives a real advantage in terms of performance, compactness and reliability.

With strong expertise in designing fiber lasers and fused fiber components, ALPhANOV is supplying end-treatment solutions to PCF (Photonic Crystal Fiber). Such fiber preparation includes PCF connectors, sealed and cleaved PCF, end-capped PCF and PCF with mode-adaptors.

ALPhANOV can address any PCF or special fiber, ranging from active double-clad large mode area fibers, to passive PCF such as hollow-core fibers and nonlinear PCF.
