its the mangaka Tsugumi Ohba's only work. (Some say its a alias from a gag mangaka Hiroshi Gamō who really hasn't done anything that good.
Mad house which is the company that produced it from a manga to an anime has done a fair bit of work. None of which that is really reminiscent of Death Note but check out Black Lagoon which is pretty good.
If you want something that is similar to Death Note watch Code Geass, its basically Death Note + Giant Robots with a bi polar mood. The first series came out back in 05, the 2nd series Code Geass - R2 is currently airing
