Abstract

A photothermal transducer based on three-dimensional (3D) thermal management was proposed. Utilizing the 3D microstructures fabricated on the transducer, the heat diffusion rate on in-plane and out-of-plane direction could be modulated and the thermal properties of the photothermal transducer could be greatly improved. The measured results were in good agreement with the simulation results. Compared to the 2D photothermal transducer, the proposed 3D photothermal transducer with isolation trenches exhibited superior advantages in thermal crosstalk and temperature contrast ratio. The proposed transducer had potential to achieve high temperature contrast, fast time response and ultralarge array scale.
