Optical waveguides in photonic integrated circuits are traditionally passive elements merely carrying optical signals from one point to another. These elements could contribute to the integrated circuit functionality if they were modulated either by variations of the core optical properties, or by using tunable claddings. In this work, the use of l...

Photonic integrated circuits (PICs) are devices that integrate multiple photonic functions. The visible light is guided between components by light waveguides of the same order as light wavelength, i.e. 1-5μm or even less [1]. Because of the size of connections, coupling light into PICs is a challenging task previous to characterizing them. The aim...

Many photonic devices are based on waveguides (WG) whose optical properties can be externally modified. These active WGs are usually obtained with electrooptic materials in either the propagating film (core) or the substrate (cladding). In the second case, the WG tunability is based on the interaction of the active material with the evanescent fiel...

Question
I'm looking for a method to attach APBA to a SU-8 surface. Until now, I'm not very successful in the process.
The SU-8 is a 1um film deposited over a surface. I'm trying to immerse the substrate in 80mM of APBA in ethanol.
Can you give me an advice?
Kind regards.
PS: Chemical molecules and suppose reaction

I need to spin coating on a surface of PDMS but all the polymers that I used can't stick. Anyone knows any surface treatment to stick something in PDMS.
I tried with UV cleaner but didn't work.
Thanks
