An　aluminum　grating　with　period　of　152　nm　is　designed　and　manufactured　based　on　rigorous　coupled　wave　analysis.　Its　transmissions　of　TM　and　TE　waves　are　measured　at　532　nm,　632.8　nm　and　810　nm,　respectively.　From　the　agreement　between　the　experimental　results　and　simulations,　a　grating　thickness　of　80　+/-　5　nm　can　be　determined.　The　analysis　of　and　experiments　on　the　grating　temperature　dependence　reveal　its　thermal　stability　in　ambient　conditions.
