Abstract

A compact thermometer based on a broadband microfiber coupler tip is demonstrated. This sensor can measure a broad temperature interval ranging from room temperature to 1283 °C with sub-200 μm spatial resolution. An average sensitivity of 11.96 pm/°C was achieved for a coupler tip with ∼2.5 μm diameter. This is the highest temperature measured with a silica optical fiber device.
