Highly-Chirped Bragg Gratings for Integrated Silica Spectrometers
James W. Field, Sam A. Berry, Rex H. S. Bannerman +4
A blazed chirped Bragg grating in a planar silica waveguide device was used to create an integrated diffractive element for a spectrometer. The grating diffracts light from a waveg…

Zn-indiffused diced ridge waveguides in MgO:PPLN generating 1 watt 780 nm SHG at 70% efficiency
Sam A. Berry, Lewis G. Carpenter, Alan C. Gray +2
We present a metallic zinc indiffused diced ridge waveguide in magnesium doped periodically poled lithium niobate (MgO:PPLN) capable of generating over 1 W of 780 nm with 70% effic…
