Inflationary gravitational waves (GW) contribute to the curl component in thepolarization of the CMB. Cosmic shear--gravitational lensing of the CMB--converts a fraction of the dominant gradient polarization to the curlcomponent. Higher-order correlations can be used to map the cosmic shear andsubtract this contribution to the curl. Arcminute resolution will be requiredto pursue GW amplitudes smaller than those accessible by Planck. The finitecutoff in CMB power at small scales leads to a minimum detectable GW amplitudecorresponding to an inflation energy near 10^15 GeV.Comment: 4 pages, 2 figures; Final version accepted for publication in Phys.
