Loew, who has coached Germany since 2006, has a contract until just after the Euro 2012 tournament, to be held in the Ukraine and Poland, but after guiding his team to third place at last year's World Cup he is eyeing Brazil in 2014.
With Bayern Munich set to part ways with coach Louis van Gaal at the end of the season, Loew removed himself as a potential replacement and said he is focused on Germany with his team top of their Euro 2012 qualifying group.
"We see good prospects for the national team with a good crop of young players," Loew told German magazine Sport Bild in an interview set to appear on Wednesday.
"The German Football Federation (DFB) agree with our philosophy of football and from there it is assumed we will keep working together through Euro 2012 and beyond.
"The European Championships are a stepping stone towards the 2014 World Cup in Brazil."
He wants to make sure a contract extension is formalised long before the end of Euro 2012 -- which culminates in the final in Kiev on July 1 2012 -- and avoid the previous negotiation problems last seen in February 2010.
Loew and the DFB failed to agree terms at the beginning of last year, when his contract was last under renewal, and a deal was only done after the World Cup last July, as Germany came third.
"I think that we want to avoid a situation similar to 2010 when it was decided to continue working together after the World Cup," said Loew whose side play Kazakhstan in a Euro 2012 qualifier on March 26 in Kaiserslautern.
"The issue was a constant presence during the tournament and we want to avoid that for Euro 2012."
DFB president Theo Zwanziger welcomed the news Loew is keen to stay on.
"From my point of view, Joachim Loew should stay on as coach for a long time," Zwanziger said.
"He has left his mark on the team. As soon as he feels the time is right, we'll talk."
Loew has said he would not consider carrying out his national team coach role alongside the the soon-to-be vacant Bayern job.
"No, that is out of the question for me," said the 51-year-old.
"It is possible, as Guus Hiddink showed by coaching both Chelsea and Russia's national team for some time.
"But in our country, it doesn't work.
"The DFB job alongside coaching Bayern, Dortmund or Bremen, that just wouldn't be possible. That would conflict with the interests of the league.
"I can never allow myself to be accused of bias for a player of a certain club."
