- W2894441842 abstract "In this paper, we demonstrate a radiation-strength-chirped metasurface centimeter-long grating antenna, whose beam quality is approaching the diffraction limit in its footprint with 90 percent efficiency.Instead of chirping the duty cycle to tune radiation strength, which calls for non-scalable fabrication resolution, we design a 2D fish-bone surface grating with apodized width of the bone.The meta surface is made by silicon nitride on top of silicon waveguide to weakly perturb the mode. Moreover, a Monte Carlo Markov Chain(MCMC) algorithm is implemented to design the radiation strength profile, making the optimized trade off between efficiency, beam quality and fabrication challenge. A metal mirror is designed to deposit on the top of the cladding for unidirectional upside-down radiation and uniform lateral gain. For the 1cm grating, our design is for a 0.01 degree beam with 37000 1D directional gain and 90% efficiency, with 200nm feature size. Finally, we fabricated the antenna and measured the beam quality with Fourier imaging system, which gives result of 0.02 degree -10dB beam divergence. To the best of our knowledge, this is the state-of-the-art on-chip antenna with CMOS- foundry-compatible technology." @default.
