Abstract

Substrate-mode holograms (SMHs) have been suggested for use in optical interconnect applications. These components combine holographic gratings with a total internal reflected beam and separate optical beam shaping from beam translation functions. This separation maintains free-space beam propagation characteristics and can help to reduce alignment tolerance requirements. This paper presents methods for the design and fabrication of a multiplexed beam-splitting substrate-mode holographic input coupler. The dichromated gelatin process was characterized to achieve a common Bragg angle for all diffracted beams. Multiplexed SMH fabrication showed that the beam ratio could be controlled with high total efficiency.
