Launched at OFC, the system uses a non-contact optical coupling which, the company says together with the connector design, helps to provide reduced sensitivity to dust.
The use of optical coupling, most commonly seen in smartphones, also minimises reflection and eliminates air gaps and their associated issues, such as debris and moisture.
It has been proved in our previous works [28-31] and other reports [32-34] that the ultrathin Ag film with a suited optical coupling layer could meet the requirements of a transparent electrode.
While the analysis was successfully performed on a detection volume < 1 [micro]L, the optical coupling losses between components caused a 53.9% optical loss per pass.
According to the Bragg condition, the incident angle 0 of the grating coupler has considerable influence on optical coupling. To facilitate system integration, most studies aim to reach [theta] = 0[degrees] with a high coupling efficiency and a wide bandwidth.
