Optical guided mode resonance filter on a flexible substrate

Abstract

Abstract:We demonstrate the operation of a flexible optical filter based on guided mode resonances that operates in the visible regime. The filter is fabricated on a free standing polymeric membrane of 1.3 μm thickness and we show how the geometrical design parameters of the filter determine its optical properties, and how various types of filter can be made with this scheme. To highlight the versatility and robustness of the approach, we mount a filter onto a collimated fibre output and demonstrate successful wavelength filtering.

High Performance, Biocompatible Dielectric Thin‐Film Optical Filters Integrated with Flexible Substrates and Microscale Optoelectronic Devices

“…is 4 . The optical characteristics of our flexible filters are also superior to other reported ones . Contour plots of measured and simulated transmission spectra at various incident angles for filters on PDMS are presented in Figure c,d, respectively.…”

“…In addition, high temperature and the potential use of ion beam bombardment to assist the film deposition are incompatible with many inorganic‐ and organic‐based devices as well as flexible, stretchable, and biocompatible substrates . Filter structures can also be directly fabricated onto flexible substrates or formed by incorporating dye molecules or pigments directly into organic polymer films . However, these demonstrated flexible filters exhibit optical performance inferior to their counterparts on rigid glass substrates.…”

Design and applications of flexible photonic membranes

“…Recently, we demonstrated the fabrication of a flexible filter based on guided mode resonances (GMR) mounted onto a aluminium foil frame, wrapped over the end of a fibre terminated with a compact collimating package. 20 Here we demonstrate a filter design that eliminates the need for the collimator, by creating an angularly robust filter.…”

Holography Using Curved Metasurfaces

“…These properties make MSs easily exploitable in flexible designs. Examples of these applications include cloaking, lab-on-fiber, optically active, and filtering devices [18][19][20][21][22][23].…”
