Abstract.  We report a simple and complete approach to estimate macrobending losses in index-guiding photonic crystal fibers with given optogeometrical parameters. The approach is based on a previously developed simpler formulation of their effective cladding indices valid in the entire single mode region of such fibers. To check the validity of our approach, we compare our results with those obtained by an earlier scalar effective index method which is not so easily accessible. We observe our results to match fairly well with the available results. Our approach should find wide attention by system designers for its ease of use.
