What country are you in? When I graduated in Elec Eng in the UK there were plenty of big companies like banks, government, utilities taking graduates of all kinds to train them into software engineering. I've met plenty of SWE with degrees in history, music, or people with no degree who've started doing manual testing or admin and got into automation and then software. Equally, if you already have the skills and can pass their test I'm sure they won't care what degree you have, physics shows a high level of technical comprehension and analysis as well as hard work.
