Title:
NANOWIRE OPTICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/100611
Kind Code:
A1
Abstract:
A nanowire optical device comprising: a plate-like photonic crystal body provided on a substrate; an optical waveguide composed of a plurality of linearly-disposed line defects constituted by portions with no lattice elements of the photonic crystal body; a groove formed in the optical waveguide along the wave-guide direction; a nanowire made from a semiconductor and arranged in the groove; an n-type region formed at one end of the nanowire; a p-type region formed at the other end of the nanowire; an active region formed between the n-type region and p-type region of the nanowire; a first electrode connected to the n-type region; and a second electrode connected to the p-type region. At least either a region in contact with the n-type region of the first electrode or a region in contact with the p-type region of the second electrode is made of a transparent electrode material.
