Abstract
The properties of what is, to the best of our knowledge, the first ten-element polarization-dependent transmission trap detector consisting of silicon photodiodes are described. The responsivity and the transmittance of the photodetector were measured at laser wavelengths of 476.2 and . In particular, the effect of the polarization state of the incident radiation on the transmittance was determined. Differences in transmittance of an order of magnitude were observed between s and p polarization. These values were compared with theoretical values calculated using the Fresnel reflection formulas. The difference between the calculated and measured values was less than . The spatial nonuniformity of the response was measured to be less than . The transmittance was measured to be spatially uniform across a area of the trap detector aperture to within for s-polarized input and within for p-polarized input.
