Abstract
We present a one-step replication technique for optical gratings that allows the control of the corrugation height and period. By using an ink that slowly condenses into a multilayer polymer, it is possible to control the corrugation height by changing the condensation time. In addition, by applying a mechanical strain on the stamp, it is also possible to change the period of the grating. The combination of these two features added to the ease of use and low cost of this technique makes it very attractive for the fast prototyping of optical gratings for applications such as the measurement of surface plasmon band gaps. Corrugation heights in the range of 100 to 250 nm and period variations up to 10% are achieved.
