Abstract: |
Hyperbolic metamaterials (HMMs) have been used to demonstrate extreme sensitivity biosensing by exciting their high-k modes. However, momentum couplers such as sub-wavelength diffraction grating or bulky high-index prism is required to excite these non-radiative modes, which is not cost-effective and thus not suitable for point-of-care applications. Here, we propose and experimentally demonstrate a cost-effective and scalable HMM-based sensor platform, by exciting the Brewster mode of the HMM from the free-space. We show the excitation of Brewster modes in a multilayered HMM comprised of alternating thin layers of TiN and phase change material such as Sb2S3. Brewster modes in the hyperbolic region occur due to abrupt phase change, and enhanced Goos-Hänchen shift is realized at the Brewster angle. The enhanced refractive index sensing is demonstrated by exploiting the singular phase of light associated with the Brewster mode of the proposed HMM. This microfluidics integrated lithography-free nanophotonic device could be a potential sensor platform for a cost-effective development of label-free biosensors for point-of-care applications. |
