Aspects of N=2 Super-W_n Strings

We construct $N=2$ super-$W_{n+1}$ strings and obtain the complete physical spectrum, for arbitrary $n \ge 2$. We also derive more general realisations of the super-$W_{n+1}$ algebras in terms of $k$ commuting $N=2$ super energy-momentum tensors and $n-k$ pairs of complex superfields, with $0\le k \le [\ft{n+1}{2}]$.
