According to L. Susskind in his GR lecture series, a photon has a gravitational field around it. This is intuitive to me as well. The photon has energy, therefore it curves space-time. I have searched, but I cannot find any sources which discuss the nature of the field.
If we call the x-axis in rectangular coordinates the trajectory of the photon, what is its gravitational field?
