Golden Boy's chief executive Richard Schaefer says he is hoping to set up a December 7 clash against American Alexander when he travels to Dubai next month.
Alexander has a record of 25 wins from 26 bouts, with 14 victories coming inside the distance and was supposed to have fought unbeaten Sheffield boxer Kell Brook last month but the fight was called off after being postponed for a third time.
Schaefer told Sky Sports' Ringside: "I know Devon is on board, Amir is on board (and) we're thinking December 7 for the fight.
"So now what we're looking at is a possibly that the fight will be in Dubai if we can structure it in a way that it is enticing for Devon Alexander to go there.
"I'm actually going to be going to Dubai and meet with the people there in July and will find out if we can get a deal done for the world title fight to be in Dubai which would be spectacular."
Alexander won the IBF title from American compatriot Randall Bailey last October after battling his way back to the top since his only defeat, to Tim Bradley in January 2011.
Colchester welterweight Lee Purdy, the injured Brook's replacement, was pulled out after seven rounds of his non-title bout against Alexander in Atlantic City, New Jersey last month after being outboxed by the US southpaw.
Purdy had failed to make the weight but there should be no such problems for Khan, himself on a road back to redemption.
The Bolton man climbed off the canvas impressively to beat Mexico's Julio Diaz in April in Brook's hometown of Sheffield in his latest victory.
He had lost his WBA and IBF light-welterweight titles to Lamont Peterson in 2011 in Washington DC, before being reinstated as champion after the American failed a drugs test.
However, the 26-year-old Englishman lost the belts again in July 2012 when he was stopped in round four by Philadelphia's Danny Garcia.
