Abstract

A tapered hollow waveguide multiplexer is proposed to combine the output of a GaInAs/GaAs multi-wavelength VCSEL array for coupling into a multi-mode fiber. The design of the proposed hollow waveguide is presented based on ray optics. We demonstrate multiplexing of 4-channel output of a GaInAs/GaAs VCSEL array formed on a patterned substrate for coupling into a multi-mode fiber. The proposed hollow waveguide multiplexer is useful for realizing compact and low-cost WDM transceiver with a multi-wavelength VCSEL array for high capacity short reach optical networks.
