Description
Summary:This report results from a contract tasking Crystal Fibre A/S as follows: TASK 1: Crystal Fibre will conduct research and development of large mode area, dual clad Er-doped photonic crystal fiber with the design and specifications to be provided by the HQ USAFA/DFP. The intention is to do one fiber type in both a passive and active (Er-doped) version - totally 2 (two) fibers, with up to three samples for each. The fiber is intended to be a tuned cladding design where smaller cores in the cladding region are designed to resonantly couple to higher order modes in the central active core, thereby improving beam quality. The fiber is designed to be polarization maintaining (PM). Nominal fiber designs will include a 19 cell core with nominal specifications of 300 micron 0.6 NA pump core, and signal core diameter to be defined. Crystal Fibre shall fabricate one preform and draw fiber for both the active and passive fiber. Samples may be sent to HQ USAFA/DFP for further testing and characterization. TASK 2: Crystal Fibre shall provide characteristics of the fiber fabricated to include core and cladding diameters, core and cladding numerical apertures, erbium doping concentration, and pump absorption at 1535nm. TASK 3: Crystal Fibre A/S will pay customs and duties associated with shipment of any samples or reports delivered to the HQ USAFA/DFP up to an amount of 500 USD for each of up to six shipments.
