Abstract
A new type of fiber optic directional coupling device is presented, designed specifically for hard-clad silica ( HCS ) fiber. Typical excess loss of couplers with 50% coupling ratio is 0.15 dB, with devices with this performance specifications being made using different sizes of hard-clad silica fiber. Tests show that the couplers have very stable temperature response, a flat coupling ratio spectrum and high directivity.
