  In this paper, we consider the complex Ginzburg Landau equation
  $$ \partial_t u = (1 + i \beta ) \Delta u + (1 + i \delta) |u|^{p-1}u -
\alpha u \text{ where } \beta, \delta, \alpha \in \mathbb R. $$
  The study aims to investigate the finite time blowup phenomenon. In
particular, for fixed $ \beta\in \mathbb R$, the existence of finite time
blowup solutions for an arbitrary large $|\delta|$ is still unknown.
Especially, Popp, Stiller, Kuznetsov, and Kramer formally conjectured in 1998
that there is no blowup (collapse) in such a case. In this work, considered as
a breakthrough, we give a counter example to this conjecture. We show the
existence of blowup solutions in one dimension with $\delta $ arbitrarily given
and $\beta =0$. The novelty is based on two main contributions: an
investigation of a new blowup scaling (flat blowup regime) and a suitable
modulation.
