Presentation / Conference Contribution
Fuentes-Dominguez, R., He, F., Cousins, R., Mellor, C. J., & Gordon, G. S. D. (2022, January). Transfering ultra-Thin metallic metasurfaces to fibre endoscope probes for advanced imaging. Presented at SPIE Photonics West 2022, San Francisco, California, USA

In this paper we present a method to transfer ultra-Thin polymer-encapsulated metallic metasurfaces onto optical fibers to enable ultra-Thin imaging devices. The metasurface is first produced by conventional e-beam lithography on a silicon substrate...

Diffractive metasurface light-shaping from fiber endoscope probes for increased depth of field
Presentation / Conference Contribution
He, F., Gordon, G., Fuentes-Dominguez, R., Cousins, R., Mellor, C. J., Barton, J. . K., & Gordon, G. S. . D. Diffractive metasurface light-shaping from fiber endoscope probes for increased depth of field. Presented at Endoscopic Microscopy XVIII, San Francisco, USA

In applications such as optical coherence tomography, there is a need both to achieve large depth of field by light shaping and to maintain ultracompact form factors. Flat metasurfaces on optical fibers can achieve such requirements, with designs suc... Read More about Diffractive metasurface light-shaping from fiber endoscope probes for increased depth of field.
