We propose and investigate a novel splice-free fiber laser array architecture that uses a double-core fiber where one of the cores is active and the other is passive. Fiber tapers were implemented to transmit the light at the pump and signal wavelengths between cores. Experimental results on coupling between cores are presented for two different fibers. A two-element monolithic fiber laser array is demonstrated.
