Title:
フォトニック結晶ベースのセンサ、試験装置、センサの形成方法、センサを使用する方法
Document Type and Number:
Japanese Patent JP7377301
Kind Code:
B2
Abstract:
A sensor for use in biosensing is disclosed. The sensor (50) comprises a photonic crystal waveguide (9; 52) comprising a photonic crystal (10; 53) comprising holes (11; 54) in a layer (12; 55) of dielectric material and a waveguide (13; 57) in the photonic crystal. The sensor comprises at least one strip (18; 591, 592, 593) disposed on the photonic crystal waveguide, spaced apart along, and running across the photonic crystal waveguide so as to form respective strip cavities (19; 601, 602, 603), each of the at least one strip including a respective layer of material for sensing presence of a respective analyte; and a slot (14; 58) running along the waveguide (13; 57) of the photonic crystal waveguide (9; 52; 152).
