  Photoemission in the system of linear charged chains has been studied with
the dipole matrix incorporated, from which its dependencies on the
photoelectron momentum (${\bf k}$), photon polarization ($\hat{\bf E}$), and
photon energy ($\omega$) can be explored. The used model is the
three-dimensional array of noninteracting chains, which is so simple as to
allow an analytic approach. Motivations of the study are for the doped CuO$_3$
chain in PrBa$_2$Cu$_3$O$_7$ and the doped static stripe phase in La$_{\rm
2-x-y}$Nd$_{\rm y}$Sr$_{\rm x}$CuO$_4$. The one-dimensional dispersion
exhibiting spin-charge separation and its dependence on the momentum
perpendicular to the chain and its $\hat{\bf E}$-dependency as well are
discussed in PrBa$_2$Cu$_3$O$_7$. For La$_{\rm 2-x-y}$Nd$_{\rm y}$Sr$_{\rm
x}$CuO$_4$, the anomalous spectral distribution formed by two sets of stripes
perpendicular to each other is investigated. The geometric effects led to by
the dipole transition matrix including the interference of photocurrents from
different chains are found to change the simple one-dimensional feature
drastically. We find these changes are consistent with experiment for the chain
system PrBa$_2$Cu$_3$O$_7$, but less satisfactory for the stripe phase in
La$_{\rm 2-x-y}$Nd$_{\rm y}$Sr$_{\rm x}$CuO$_4$. This means that in the stripe
phase much two-dimensional characters still exist unlike the chain system.
