Abstract :
Novel fiber laser design strategy is proposed based on in-phase mode selection in a circular antiguided resonant structure. A complete set of guided modes of the structure was calculated using 2D mode solver. Parameters of 7-core array are found providing the maximal gain overlap factor for the in-phase mode.
