Abstract: An optical device has a housing for receiving a plurality of optical fibers adapted to carry optical signals. A filter is disposed within the housing for transmitting specific optical signals having a predetermined wavelength range. A first ball lens is coupled to the housing and is positioned relative to the filter and the optical fibers to selectively collimate and focus the optical signals. A second ball lens is coupled to the housing and is also positioned relative to the filter and optical fibers to selectively collimate and focus the optical signals. Both ball lenses are optically coupled to the filter.

Abstract: The present invention is a three-dimensional tapered waveguide coupler capable of interconnecting electro-optical devices with differing optical mode profiles. The ends of the waveguide are configured to match the optical mode profiles of the electro-optical devices that the waveguide interconnects. The waveguide adiabatically transmits the fundamental mode of the photo-optic signal from the electro-optical device at the waveguide's input end to a different electro-optical device at the waveguide's output end. A single coupler can be configured with one or more waveguides, each waveguide having different optical mode profiles at either end and different optical transmission characteristics.
