contents We develop a two-parameter family of flat-spacetime modes labeled by a deformation scale $κ$ and a phase angle $γ$, extending the $κ$-plane wave framework to include complex squeezing. The resulting $κγ$ basis provides a globally well-defined mode decomposition whose associated vacuum $|0_{κ,γ}\rangle$ is a continuous-mode phase-squeezed state: $κ$ fixes the squeezing magnitude, while $γ$ sets the squeezing angle in phase space. We identify phase-induced particle creation, in which a relative phase mismatch $Δγ$ between observers generates a nontrivial particle spectrum governed by $(κ,Δγ)$ even when $κ$ is held fixed. We then derive the two reciprocal Bogoliubov maps: the $κγ$ plane-wave operators in terms of $κ'$-Rindler operators, and conversely the $κ'$-Rindler operators in terms of $κγ$ plane-wave operators, providing a closed algebraic bridge between these bases. Finally, by analyzing the Wightman function we show that $|0_{κ,γ}\rangle$ is globally regular, with no singularities beyond those of the standard Minkowski vacuum.
