Abstract

We report here experimental demonstration of Fano resonance photonic crystal Si membrane reflectors on diamond for much improved thermal performance. At normal incidence, high reflection is obtained over a broad spectral band, with reflectivity greater than 95% from 1260 to 1450 nm. The measured reflection spectrum agrees well with the theoretical design. The improved thermal performance, with much reduced temperature rise, was also observed experimentally over a wide range of high incident optical power intensities. Such athermal Si membrane reflectors on diamond offer great opportunities for the applications in energy efficient lasers and high-power lasers.
