Abstract :
We report the first high-current photodiode based on the slab-coupled optical waveguide concept. The device has a large mode (5.8 times 7.6 mum) and ultra-low optical confinement (Gamma ~ 0.05%), allowing a 2-mm absorption length. The maximum photocurrent obtained was 250 mA (R = 0.8-A/W) at 1.55 mum.
