The ContinuousWave sourcetime, if the DC component is zeroed out, has the following formula:

$A(1+e^{-\frac{(t-t_o*t_w)}{t_w}})^{-1}e^{i\phi}e^{-i\omega_0 t}$
where $A$ is the amplitude, $t_o$ is the time offset, $t_w=\frac{1}{2\pi f_{width}}$ is the width of the pulse in seconds, $\phi$ is the phase shift, and $\omega_0=2\pi f_0$. See the code [here](https://docs.flexcompute.com/projects/tidy3d/en/latest/_modules/tidy3d/components/source/time.html#ContinuousWave).
