Publication number: 20090231701Abstract: Optical isolators are used in optical communication systems, especially optical systems which employ semiconductor lasers. As transmission rates used in optical communications systems have increased, for example to several Gbits per second, the performance required of lasers used in such systems has also increased. It is well known that light reflected back from some parts of an optical communications system will adversely affect the operation of such a high performance laser leading to fluctuations in the spectrum, line width, or intrinsic noise of the laser. In this invention, a free space isolator is illustrated utilized to protect such high performance semiconductor lasers from these reflections by stabilizing an optical element within a base.Type: ApplicationFiled: March 13, 2008Publication date: September 17, 2009Inventor: Kun Hua
