Implication

Experimental study demonstrates high-efficiency grating couplers in polymer waveguides, indicating viable manufacturing for all-polymeric optical chips.

Key Points

Investigate high-efficiency grating couplers fabricated via electron-beam lithography and embossing replication for polymer slab and strip waveguides.
Fabricated grating couplers on polymer waveguides using direct-write electron-beam lithography, followed by replication into polymer substrates via embossing.
Engineered gratings with variable depths, blazed profiles, and line curvature corrections to match light emission to a Gaussian profile and optimize focusing.
Achieved a maximum input coupling efficiency of 67% into polymer slab waveguides.
Demonstrated a focusing blazed grating with curvature correction that couples light into a polymer strip waveguide with 42% efficiency.
Successfully tailored the outcoupled light intensity into a Gaussian-like distribution and realized an all-polymeric optical chip.
