We describe ab initio calculations of doubly strange s-shell hypernuclei ({sub {lambda}}{sub {lambda}}{sup 4}H, {sub {lambda}}{sub {lambda}}{sup 5}H and {sub {lambda}}{sub {lambda}}{sup 6}He) by using a set of fully coupled channel potentials. The wave function includes {lambda}{lambda}, {lambda}{sigma}, N{xi} and {sigma}{sigma} channels. Minnesota NN, D2' YN, and simulated YY potentials based on the Nijmegen hard-core model, are used. Bound-state solutions of these systems are obtained. We calculate the probabilities of the exotic components such as N{xi}, {lambda}{sigma} and {sigma}{sigma}. This is a first attempt to explore the few-body problem of the full-coupled channel scheme for these systems.
