Diamond Bragg Grating Waveguides

Our realisation of laser written Bragg grating waveguides in diamond is to appear in the upcoming issue of Optics Letters.

In collaboration with Politecnico di Milano, we have been able to fabricate laser written sub-surface waveguides in diamond with an integrated Bragg grating for spectral filtering. This proof-of-principle work achieved narrow-band spectral reflection in the telecommunication band from a fourth order grating. Access the paper here.
