Title:
GRAPHENE GROOVE WAVEGUIDE PHOTODETECTOR
Document Type and Number:
WIPO Patent Application WO/2016/106731
Kind Code:
A1
Abstract:
Provided is a graphene groove waveguide photodetector. The graphene groove waveguide photodetector has higher detection responsivity and photoelectric conversion efficiency than a common graphene waveguide photodetector. The graphene groove waveguide photodetector comprises: a lower sleeve layer (10); at least two core layers (11) disposed on the lower sleeve layer (10) at an interval, at least one core layer (11) of the at least two core layers (11) being in contact with the lower sleeve layer (10); groove layers (12) disposed on the lower sleeve layer (10) and between adjacent core layers (11), the number of the groove layers (12) being greater than or equal to 1, and the refractive index of each groove layer (12) being less than the refractive index of two core layers (11) adjacent to the groove layer (12); and a grapheme layer (13) and two metal electrodes (14), the grapheme layer (13) being in contact with at least one groove layer (12) of the groove layers (12) or the grapheme layer (13) being disposed in at least one groove layer (12) of the groove layers (12), and the grapheme layer (13) being in contact with at least one metal electrode (14) of the two metal electrodes (14).
