High coupling efficiency, passive alignment setup for visible-range fiber-to-waveguide edge coupling

Development of nano- and microdevices for the next generation of biotechnology, wearables and miniaturized instrumentation

“…Various optical approaches have been reported in this research field, such as the use of modified silica substrates, surfaces, waveguides, optical resonators and other setups, which contribute to the design of functional devices. 23 In this context it could be noted for example how the control of nanochemistry has allowed to modify light scattering properties. The capability to organize hybrid silica NPs towards hybrid silica nanoarrays could lead to modified surfaces and substrates for improved light scattering resonances and increased signaling from the surface, across and through the materials by means of different approaches such as photonics surfaces, materials and waveguide substrates respectively.…”
