Abstract
An optical transmitter relaxes the tolerance between a source assembly and a fiber receptacle to facilitate passive alignment. The source assembly includes a light source and a lens. The lens is held at a fixed distance away from the light source using precise support structures typically formed by photolithographic processes. The fiber receptacle includes an optical element. The fiber receptacle is adapted to hold an optical fiber at a fixed distance from the optical element. The lens substantially collimates light from the light source into the form of collimated light. The optical element focuses the collimated light onto the aperture of the optical fiber.
