Abstract

A standard optical power meter has been developed that can be used to measure light from optical fibers as well as light beams. The optical detector element in this power meter consists of NiP optical absorption material, which has an ultralow reflectance and high reliability, and a μc-Ge:H film with excellent thermoelectric conversion efficiency characteristics. This standard optical power meter has a response time of 1.8 seconds, which is 1/3 the response time of conventional thermal detector elements, and a high accuracy of ±1.5% or better when measuring in the -15 dBm to +10 dBm level range at wavelengths of 0.4 μm to 1.8 μm
