Abstract: In one aspect, an optical device comprises a monolithic optical module which includes a first total internal reflection (TIR) surface, a second TIR surface adjacent the first TIR surface, and a first optical port aligned with the first internal optical beam dividing interface. An interface between the first TIR surface and the second TIR surface forms a first internal optical beam dividing interface. An exterior surface of the first TIR surface and an exterior surface of the second TIR surface form a generally V-shaped notch on the monolithic optical module. A first optical beam entering the monolithic optical module through the first optical port and incident on the first internal optical beam dividing interface is partially reflected by the first TIR surface to travel in a first direction as a second optical beam and partially reflected by the second TIR surface to travel in a second direction as a third optical beam. The second direction is generally opposite to the first direction.

Abstract: Various embodiments of a novel method and design for coupling optical signals from a lens array to a fiber array subassembly with locking capability in a pluggable form factor are provided. Optical signals vertically emitted from a vertical-cavity surface-emitting laser (VCSEL) array on a printed circuit board (PCB) are coupled into an optical coupling lens array, which are then coupled into a fiber array subassembly parallel to the PCB. A locking device in a pluggable form factor provides means for mating and locking between the lens array and the fiber array subassembly, thereby achieving good coupling and locking between the fiber array subassembly and lens array.

Abstract: A low-cost monolithic optical module for splitting one or more input optical beams to two or more output optical beams is provided. The one or more input optical beams are reflected by two or more total internal reflection (TIR) surfaces of the monolithic optical module. A light splitting ratio between the two or more output optical beams is predetermined by one or more physical features of the two or more TIR surfaces.
