complex numbers - $(1+i)(e^{(1+i)phi})$ expressed in polar and rectangular form

$$(1+i)(e^{(1+i)\phi})$$

I need to express this in both polar and rectangular form, but the difficult part is that extra $i$ above the $e$. Also, what am I supposed to make of $\phi$? We normally use $\theta$ to represent the argument of a complex number, so would this just be another notation for the angle?

Would the final answer in rectangular form not have a $\phi$ in it?
