A centrosymmetric multilayer stack of two transparent materials, which is embedded in a high-index prism, can function as a complete-transmission quarter-wave or half-wave retarder (QWR or HWR) under conditions of frustrated total internal reflection. The multilayer consists of a high-index center layer sandwiched between two identical low-index films with high-index-low-index bilayers repeated on both sides of the central trilayer, maintaining the symmetry of the entire stack and constituting a QWR (Delta(t)=90 degrees or 270 degrees ) or HWR (Delta(t)=180 degrees ) in transmission. A QWR design at wavelength lambda=1.55 microm is presented that employs an 11-layer stack of Si and SiO(2) thin films, which is embedded in a GaP cube prism. The intensity transmittances for the p and s polarizations remain &gt;99% and Delta(t) deviates from 90 degrees by &lt;+/-3 degrees over a 100 nm spectral bandwidth (1.5&lt; or =lambda&lt; or =1.6 microm), and by &lt; or =+/-7 degrees over an internal field view of +/-1 degrees (incidence angle 44 degrees &lt; or = phi(0)&lt; or =46 degrees inside the prism). An HWR design at lambda=1.55 microm employs seven layers of Si and SiO(2) thin films embedded in a Si cube, has an average transmittance &gt;93%, and Delta(t) that differs from 180 degrees by &lt;+/-0.3 degrees over a 100 nm bandwidth (1.5&lt; or =lambda&lt; or =1.6 microm) and by &lt;+/-17 degrees over an internal field view of +/-1 degree . The sensitivity of these devices to film-thickness errors is also considered.
