(Received 2 June 1998)
We present analytical and numerical results related to partially coherent solitons (PCS) of a novel
class. In effect, there is freedom to choose the shape of a PCS as it is governed by 2N 2 1 parameters,
where N is the number of linear modes contributing to the soliton. In particular, we show that a
PCS may have an asymmetric shape. The PCS shape becomes arbitrary in the limit of complete
incoherence. Another remarkable new feature of a PCS is that collisions in Kerr-like media cause
the PCS to change its shape, although each beam remains a stationary soliton after the collision.
