Patent ID: 7961391

Claim:
A method for forming an optical isolator and securing the optical isolator within a metal housing, the method comprising the steps of: bonding a first Faraday rotator directly to first and second polarizers, the first and second polarizers being bonded to opposing sides of the Faraday rotator to form the optical isolator; bonding a side of the optical isolator directly to a non-toroidal shaped glass base such that an optical signal is transmitted through opposing ends of the optical isolator without passing through the glass base; securing the glass base directly to and within a magnet ring using epoxy, wherein the side of the glass base secured to the magnet ring is correspondingly curved so as to interface with an inside diameter of the magnet ring; and securing the magnet ring within an inner diameter of the metal housing, wherein the optical isolator is positioned at an angle resulting in light reflection being blocked in one direction, the angle being caused by a slope on the surface of the glass base bonded to the optical isolator.
