The 22-year-old makes the switch to the City Ground after two successful trials with the East Midlands club.
The Frenchman has fallen out of favour at Stade Velodrome and is delighted to join manager Paul Hart's squad, as Forest aim for a return to The Premiership by earning promotion this season.
Gavanon told the club's official website: "This is a great opportunity for me and I will do everything I can to make a success of my time at the City Ground.
"I hope I can bring something a little different to the squad and make an impact on the first team between now and the end of the season."
