Abstract

A compact red-green-blue beam combiner (multiplexer) based on two-mode interference (TMI) is proposed and its feasibility is shown through three-dimensional beam propagation simulation. The first stage TMI beam combiner makes red (637 nm) and blue (446 nm) beams combined toward one output port and the second stage one combines red, blue, and green (532 nm) beams. The power transmission to the output port from the red, green, and blue input ports are 0.96, 0.99, and 0.98, respectively. When the wavelength deviation is 10 nm, the transmission is maintained to be larger than 0.9. The size of the combiner is as tiny as $0.02{\times}3.8mm^2$ .
