Abstract
We have packaged a rectangular , -thick Z-cut lithium niobate film produced by crystal ion slicing (CIS) and evaluated its performance as a pyroelectric optical detector. We justify the difficulty of preparing the film by showing that the freestanding detector has much greater sensitivity than the same detector bonded to a substrate. We compare the sensitivity of three CIS-film detectors with that of a detector based on a -thick plate and describe the detectors’ spatial uniformity and noise-equivalent power.
