  We demonstrate an optical waveguide device, capable of supporting the high,
in-vacuum, optical power necessary for trapping a single atom or a cold atom
ensemble with evanescent fields. Our photonic integrated platforms, with
suspended membrane waveguides, successfully manages optical powers of 6 mW (500
um span) to nearly 30 mW (125 um span) over an un-tethered waveguide span. This
platform is compatible with laser cooling and magneto-optical traps (MOTs) in
the vicinity of the suspended waveguide, called the membrane MOT and the needle
MOT, a key ingredient for efficient trap loading. We evaluate two novel designs
that explore critical thermal management features that enable this large power
handling. This work represents a significant step toward an integrated platform
for coupling neutral atom quantum systems to photonic and electronic integrated
circuits on silicon.
