Paper Abstract

This paper describes a channel waveguide beam splitter (CWBS) in which a single laser beam can be split into many beams using glass stripe waveguides and localized surface relief gratings. The grating element situated on top of individual 90 degree(s) T-branches couples a fraction of the backbone light down a side channel and acts as a miniature mode converter. Single-mode TE light in the backbone is converted into single-mode TM light in the side channel. The laser wavelength used in these experiments was 830 nm. Each individual grating was only a few microns in length and so the grating acceptance exhibited a large bandwidth. The total excess loss coupling the input waveguide optical power partially into 100 waveguide branches was only 0.25 dB.
