Abstract
A photonics apparatus is described. The photonics apparatus includes a plurality of components and a mounting member for mounting the components. The mounting member and the components are structured such that all of the components of the photonics module are precisely mounted and aligned on the mounting member without requiring active alignment and additional mounting member. The components mounted on the mounting member include at least a laser, a photo detector, and two spherical lenses. The components may also include an optical filter and a mirror. The mounting member is made of silicon such that a photo-lithographic masking and etching process can be used to precisely process the mounting member to mount these components. The photo detector includes an integrated mirror. The optical filter and the mirror may be integrated together to form an integrated device that is attached to the mounting member. A method of making the photonics apparatus is also described.
