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.
